Complex. This is that the concentration of one or more fillers in the region of a metal matrix composite is at least two times higher than the region at different locations of the metal matrix composite (eg, several layers or groups in the metal matrix composite) a filler). Although it is possible to observe that the one or more fillers are not exactly homogeneously distributed in a sufficiently small volume of one of the metal matrix composites in the metal matrix, the (etc.) filler is still dispersed in the metal.

用語「燒結(sinter)」是指藉由加熱粉狀材料但不完全液化以使其聚合成固體或多孔塊體。亦可選地在燒結期間擠壓該粉狀材料。 The term "sinter" refers to polymerization of a powdery material but not complete liquefaction to polymerize it into a solid or porous mass. The powdered material is also optionally extruded during sintering.

有關粒子的用語「包封密度(envelope density)」是指質量除以包封體積。該「包封體積(envelope volume)」是指各粒子中固體及該粒子中任何空隙的體積總和。同樣的,有關金屬基質複合物的用語「包封密度」是指質量除以包封體積,其中該「包封體積」是指該金屬基質複合物中固體及該金屬基質複合物中任何空隙的體積總和。 The term "envelope density" in relation to particles refers to the mass divided by the envelope volume. The "envelope volume" refers to the sum of the solids in each particle and any voids in the particle. Similarly, the term "encapsulation density" with respect to a metal matrix composite refers to the mass divided by the encapsulation volume, wherein the "encapsulation volume" refers to the solid in the metal matrix composite and any voids in the metal matrix composite. The sum of the volumes.

有關多孔粒子的用語「骨架密度(skeleton density)」是指質量除以骨架體積。該「骨架體積(skeleton volume)」是指固體材料及粒子內任何封閉孔的體積總和。 The term "skeleton density" with respect to porous particles refers to the mass divided by the volume of the skeleton. The "skeleton volume" refers to the sum of the volume of the solid material and any closed pores within the particle.

有關玻璃泡的用語「平均真密度(average true density)」是指該等玻璃泡的密度的平均而不是一體積的玻璃泡的密度(其取決於該等玻璃泡在該體積中的壓實度)。 The term "average true density" in relation to a glass bubble refers to the average density of the glass bubbles rather than the density of a volume of glass bubbles (which depends on the compaction of the glass bubbles in the volume). ).

用語「塑性降伏(plastic yield)」是指材料發生預定量的永久形變時的應力。 The term "plastic yield" refers to the stress at which a material undergoes a predetermined amount of permanent deformation.

用語「拉塑性降伏(tensile plastic yield)」是指材料經受到拉力時,該材料發生預定量的永久形變時的應力。 The term "tensile plastic yield" refers to the stress at which a predetermined amount of permanent deformation occurs when a material is subjected to a tensile force.

用語「軟化點(softening point)」是指材料(例如,處於固相)開始因為自己的重量而開始塌陷的溫度或溫度範圍。對於具有明確熔點(例如,金屬)的材料,軟化點大致上可視為金屬或金屬合金的熔點。然而,對於沒有明確熔點的材料,軟化點可以是材料的彈性行為變成塑性流的溫度。例如,玻璃、玻璃-陶瓷、或瓷的軟化點會出現在材料的玻璃-轉移溫度,而且可由黏度107.65泊所定義。一般例如以Vicat法(例如,ASTM-D1525或ISO 306)或以熱變形測試(例如,ASTM-D648)來測定玻璃的軟化點。 The term "softening point" refers to the temperature or temperature range at which a material (eg, at a solid phase) begins to collapse due to its own weight. For materials having a defined melting point (eg, metal), the softening point can be considered substantially as the melting point of the metal or metal alloy. However, for materials that do not have a clear melting point, the softening point can be the temperature at which the elastic behavior of the material changes to a plastic flow. For example, the softening point of glass, glass-ceramic, or porcelain can occur at the glass-transfer temperature of the material and can be defined by a viscosity of 10.75 poise. The softening point of the glass is generally determined, for example, by the Vicat method (for example, ASTM-D1525 or ISO 306) or by a heat distortion test (for example, ASTM-D648).

有關玻璃泡的用語「未塗佈(uncoated)」是指該等玻璃泡的外表面沒有施加任何額外的材料(亦即,具有一組成物不同於該玻璃)。 The term "uncoated" with respect to glass bubbles means that no additional material is applied to the outer surface of the glass bubbles (i.e., having a composition different from the glass).

用語「降伏強度(yield strength)」是指認為材料已經開始塑性延伸時的應力。在本文中使用時,係以0.2%的偏移判定降伏強度。ASTM B557M-15揭示「7.6降伏強度-用偏移法以0.2%的偏移判定降伏強度。接受或拒收材料可基於負載延伸法(Extension-Under-Load Method)決定。對於仲裁試驗,應使用該偏移法(offset method)。7.6.1偏移法-藉由「偏移法」判定降伏強度,需要確保可繪製應力-應變圖的資料(自動圖繪或以數值表示)。然後在應力-應變圖(圖16)標出等於偏移指定值的Om,平行OA繪製mn,因而找出r,其為mn和應力-應變圖的交點(註12)。記述以此方法得到的降伏強度時,應於用語降伏強度後在括號內記載「偏移」之特定值。如此:降伏強度(偏移=0.2%)=360MPa」。 The term "yield strength" refers to the stress at which the material is considered to have begun to plastically extend. As used herein, the fall strength is determined with an offset of 0.2%. ASTM B557M-15 reveals "7.6 Depth Strength - Determining the drop strength with an offset of 0.2% using the offset method. Acceptance or rejection of materials can be determined based on the Extension-Under-Load Method. For arbitration tests, use The offset method. 7.6.1 Offset Method - The "offset method" determines the intensity of the fall, and it is necessary to ensure that the stress-strain map can be plotted (automatic plot or numerically). Then, in the stress-strain diagram (Fig. 16), Om equal to the specified value of the offset is marked, and parallel OA draws mn , thus finding r , which is the intersection of mn and the stress-strain diagram (Note 12). When the fall strength obtained by this method is described, the specific value of "offset" is described in parentheses after the word fall strength. Thus: the drop strength (offset = 0.2%) = 360 MPa".

NEXTEL 312 and NEXTEL 440 are refractory aluminum borosilicates comprising Al 2 O 3 , SiO 2 and B 2 O 3 . NEXTEL 550 and NEXTEL 720 are aluminum silicates and NEXTEL 610 is alumina. During manufacture, the NEXTEL wire coating organic coating or finishing acts as an aid to the textile process. The coating may include the use of starch, oil, wax or other organic ingredients applied to the strands to protect and facilitate gripping. The coating can be removed from the ceramic filaments by heat cleaning the filaments or ceramic fibers, such as at a temperature of 700 ° C for one to four hours.

該等陶瓷纖維可經切削或裁剪以便提供相對均勻的長度,其可在機械剪切操作或雷射切削操作、以及在其他切削操作之中,藉由切削陶瓷材料的連續的絲來達成。鑑於如此切削操作之高度受到控制之本質,該等陶瓷纖維之尺寸分布非常狹窄,而允許控制該複合物性質。 The ceramic fibers can be cut or cut to provide a relatively uniform length that can be achieved by cutting continuous filaments of ceramic material during mechanical shearing operations or laser cutting operations, as well as in other cutting operations. In view of the nature of the control of the height of such cutting operations, the size distribution of the ceramic fibers is very narrow, allowing control of the properties of the composite.

該陶瓷纖維的長度,例如,可用裝配有一CCD Camera(Olympus DP72,Tokyo,Japan)以及分析軟體(Olympus Stream Essentials,Tokyo,Japan)之一光學顯微鏡(Olympus MX61,Tokyo,Japan)來判定。可藉由將該陶瓷纖維的代表性取樣散布在玻璃玻片上並以10X放大率測量至少200個陶瓷纖維的長度來製備樣本。 The length of the ceramic fiber, for example, can be equipped with a CCD Camera (Olympus DP72, Tokyo, Japan) and an analysis software (Olympus Stream) Optical microscopy (Olympus MX61, Tokyo, Japan), one of Essentials, Tokyo, Japan. Samples can be prepared by spreading a representative sample of the ceramic fibers onto a glass slide and measuring the length of at least 200 ceramic fibers at 10X magnification.

亦可自其他適當陶瓷氧化物絲形成陶瓷纖維。此類陶瓷氧化物絲的實例包括可購自Central Glass Fiber Co.,Ltd.的彼等陶瓷氧化物絲(例如,EFH75-01、EFH150-31)。鋁硼矽酸鹽玻璃纖維也是較佳的,其係其含有小於約2%的鹼或實質上不含鹼(亦即,「E-玻璃」纖維)。E-玻璃纖維可從許多供應商購得。 Ceramic fibers can also be formed from other suitable ceramic oxide wires.

分散在該金屬基質複合物中的不連續纖維數量沒有特定限制。該複數個纖維存在數量通常為該金屬基質複合物的至少1重量百分比、該金屬基質複合物的至少2重量百分比、至少3重量百分比、至少5重量百分比、至少10重量百分比、至少15重量百分比、至少20重量百分比、或至少25重量百分比;及至多50重量百分比、至多45重量百分比、至多40重量百分比、或至多35重量百分比的該金屬基質複合物。在某些實施例中,該等纖維存在於該金屬基質複合物之數量為該金屬基質複合物的1重量百分比與50重量百分比之間、或2重量百分比與25重量百分比之間、或5重量百分比與15重量百分比之間(含)。包括小於1重量百分比的該等纖維造成該金屬基質複合物強度極微小的上升,然而包括多於50重量百分比的該等纖維會因為該金屬基質複合物含有金屬及無機粒子的量不足而對該金屬基質複合物的包封密度造成負面的衝擊。在某些實施例中,該複數個無機粒子及該複數個不連續纖維以該金屬基質複合物的5重量百分比與50重量百分比之間(含)的數量結合存在。 There is no particular limitation on the amount of discontinuous fibers dispersed in the metal matrix composite. The plurality of fibers are typically present in an amount of at least 1 weight percent of the metal matrix composite, at least 2 weight percent, at least 3 weight percent, at least 5 weight percent, at least 10 weight percent, at least 15 weight percent of the metal matrix composite, At least 20 weight percent, or at least 25 weight percent; and up to 50 weight percent, up to 45 weight percent, up to 40 weight percent, or up to 35 weight percent of the metal matrix composite.

Between percentage and 15 weight percent (inclusive). Including less than 1 weight percent of such fibers causes a very slight increase in the strength of the metal matrix composite, however, including more than 50 weight percent of the fibers may be due to insufficient metal and inorganic particles in the metal matrix composite. The encapsulation density of the metal matrix composite causes a negative impact. In certain embodiments, the plurality of inorganic particles and the plurality of discrete fibers are present in combination between 5 weight percent and 50 weight percent of the metal matrix composite.

有利的是,該金屬基質複合物展現一減少的包封密度(和純金屬相比)以及也展現可接受的機械性質兩者。例如,該金屬基質複合物一般而言具有每立方公分1.35與2.70克之間(含)或每立方公分1.80與2.50克之間(含)的一包封密度。例如,該金屬基質複合物可具有每立方公分至少1.60克、至少1.75、至少1.90、至少2.00、至少2.10、或每立方公分至少2.25克的一包封密度;以及每立方公分至多2.70的一包封密度、至多2.60、至多2.50、至多2.40、或至多2.30克。 Advantageously, the metal matrix composite exhibits a reduced encapsulation density (as compared to pure metals) and also exhibits acceptable mechanical properties. For example, the metal matrix composite generally has an encapsulation density of between 1.35 and 2.70 grams per cubic centimeter (inclusive) or between 1.80 and 2.50 grams per cubic centimeter. For example, the metal matrix composite can have an encapsulation density of at least 1.60 grams, at least 1.75, at least 1.90, at least 2.00, at least 2.10, or at least 2.25 grams per cubic centimeter per cubic centimeter; and a package of up to 2.70 per cubic centimeter; Sealing density, up to 2.60, up to 2.50, up to 2.40, or up to 2.30 grams.

在某些實施例中,該金屬包含鋁或其合金且該金屬基質複合物具有每立方公分1.80與2.50克之間(含)的一包封密度;每立方公分2.00與2.30克之間(含);或每立方公分1.80與2.20克之間(含)。 In certain embodiments, the metal comprises aluminum or an alloy thereof and the metal matrix composite has an encapsulation density of between 1.80 and 2.50 grams per cubic centimeter; between 2.00 and 2.30 grams per cubic centimeter; Or between 1.80 and 2.20 grams per cubic centimeter (inclusive).

在某些實施例中,該金屬包含鎂或其合金且該金屬基質複合物具有每立方公分1.35與1.60克之間(含)的一包封密度;每立方公分1.55與1.60克之間(含);或每立方公分1.35與1.50克之間(含)。 In certain embodiments, the metal comprises magnesium or an alloy thereof and the metal matrix composite has an encapsulation density of between 1.35 and 1.60 grams per cubic centimeter; between 1.55 and 1.60 grams per cubic centimeter; Or between 1.35 and 1.50 grams per cubic centimeter (inclusive).

有利的是,在許多實施例中該金屬基質複合物具有比該金屬之密度小至少8%之一包封密度(或小至少10%、小至少12%、小至少15%、或小至少17%)而且在破裂前可耐受1%之應變。此性質組合既提供該金屬的輕量化且在該金屬基質複合物中維持一些該金屬特性兩者。尤其,該金屬基質複合物較佳的是於一拉伸試驗中在破壞前展現一降伏強度。在某些實施例中該金屬基質複合物具有50百萬 帕斯卡或更大、75百萬帕斯卡或更大、100百萬帕斯卡或更大、150百萬帕斯卡或更大、或200百萬帕斯卡或更大的一降伏強度。 Advantageously, in many embodiments the metal matrix composite has an encapsulation density of at least 8% less than the density of the metal (or at least 10% less, at least 12% smaller, at least 15% smaller, or at least 17 smaller) %) and can withstand 1% strain before breaking. This combination of properties provides both weight reduction of the metal and maintaining some of the metallic properties in the metal matrix composite. In particular, the metal matrix composite preferably exhibits a relief strength prior to failure in a tensile test. In certain embodiments the metal matrix composite has 50 million Pascals or a greater, 75 megapascals or greater, 100 megapascals or greater, 150 megapascals or greater, or 200 MPa or greater.

發現本揭露的至少某些例示性實施例的該金屬基質複合物展現一應力-應變曲線顯示塑性降伏行為,且本揭露的至少某些例示性實施例的該金屬基質複合物展現一應力-應變曲線顯示抗拉塑性降伏行為。也就是說,該應力-應變曲線展現一區域的塑性流。該塑性降伏曲線及抗拉塑性降伏曲線係與一純脆性破壞機制形成對比。也就是說,該純脆性行為在該應力-應變曲線內展現僅一彈性區域,而沒有(或很小)塑性流區域。令人驚訝的是,根據本揭露之至少一些實施例在金屬基質複合物中作為填料之無機粒子及不連續纖維二者之結合,於實驗提供一塑性降伏曲線及/或一抗拉塑性降伏行為。例如,參照圖3,含有纖維及多孔無機粒子二者(詳細說明如下)的實例13的應力-應變曲線在脆性破壞機制前出現降伏。在某些實施例中,該金屬基質複合物破裂前可耐受1%、1.5%、或2%之應變。此外,出乎意料的,該金屬粉末與該等多孔無機粒子保持分離,而沒有在燒結過程中被推進該等多孔無機粒子的一些細孔中(尤其是施加壓力下的燒結)。有趣的是,該等多孔無機粒子並沒有傾向於在燒結期間受損(例如,碎裂或壓碎),而是維持其多孔骨架結構。 The metal matrix composite of at least some exemplary embodiments of the present disclosure is found to exhibit a stress-strain curve exhibiting plasticity-floating behavior, and the metal matrix composite of at least some exemplary embodiments of the present disclosure exhibits a stress-strain The curve shows the tensile plasticity fluctuation behavior. That is, the stress-strain curve exhibits a plastic flow in a region. The plasticity curve and the tensile plasticity curve are contrasted with a pure brittle failure mechanism. That is, the pure brittle behavior exhibits only one elastic region within the stress-strain curve, and no (or very small) plastic flow region. Surprisingly, according to at least some embodiments of the present disclosure, a combination of inorganic particles and discontinuous fibers as fillers in a metal matrix composite provides a plasticity drop curve and/or a tensile plasticity drop behavior in the experiment. . For example, referring to Figure 3, the stress-strain curve of Example 13 containing both fibers and porous inorganic particles (described in detail below) appears to fluctuate before the brittle failure mechanism. In certain embodiments, the metal matrix composite can withstand a strain of 1%, 1.5%, or 2% prior to rupture. Furthermore, unexpectedly, the metal powder remains separated from the porous inorganic particles without being pushed into some of the pores of the porous inorganic particles during sintering (especially sintering under applied pressure). Interestingly, the porous inorganic particles do not tend to be damaged (e.g., chipped or crushed) during sintering, but rather maintain their porous framework structure.

在許多實施例中,該金屬基質複合物展現25百萬帕斯卡(MPa)或更大的一極限抗拉強度,例如40MPa或更大、50MPa或更大、75MPa或更大、100MPa或更大、150MPa或更大、200MPa或更大、250MPa或更大、或300MPa或更大。因為金屬基質複合物 的抗拉強度與金屬基質複合物的包封密度有關,一般而言一複合物輕量化的期間會犧牲抗拉強度,考慮金屬基質複合物的抗拉強度則可為進一步有用。在一些實施例中,該金屬基質複合物具有每立方公分1.80與2.50克之間(含)的一包封密度,以及50MPa或更大、100MPa或更大、150MPa或更大、200MPa或更大、250MPa或更大、或300MPa或更大的一極限抗拉強度。 In many embodiments, the metal matrix composite exhibits an ultimate tensile strength of 25 megapascals (MPa) or greater, such as 40 MPa or greater, 50 MPa or greater, 75 MPa or greater, 100 MPa or greater, 150 MPa or more, 200 MPa or more, 250 MPa or more, or 300 MPa or more. Metal matrix composite The tensile strength is related to the encapsulation density of the metal matrix composite. Generally, the tensile strength is sacrificed during the weight reduction of the composite, and the tensile strength of the metal matrix composite can be further useful. In some embodiments, the metal matrix composite has an encapsulation density between 1.80 and 2.50 grams per cubic centimeter, and 50 MPa or greater, 100 MPa or greater, 150 MPa or greater, 200 MPa or greater, An ultimate tensile strength of 250 MPa or more, or 300 MPa or more.

有利的是,在某些實施例中獲得了理想的機械性質而不需該等無機粒子及該等不連續纖維以外的填料。在如此實施例中,該金屬基質複合物基本上由一金屬、複數個無機粒子、及複數個不連續纖維所組成。該金屬基質複合物因而可進一步含有對該金屬基質複合物的機械性質沒有實質衝擊的添加物。相比之下,基本上由一金屬、複數個無機粒子、及複數個不連續纖維所組成的一金屬基質複合物不能進一步包括添加物,諸如用於幫助該等填料分散的材料。 Advantageously, desirable mechanical properties are obtained in certain embodiments without the need for such inorganic particles and fillers other than the discontinuous fibers. In such an embodiment, the metal matrix composite consists essentially of a metal, a plurality of inorganic particles, and a plurality of discrete fibers. The metal matrix composite may thus further comprise an additive that does not substantially impact the mechanical properties of the metal matrix composite. In contrast, a metal matrix composite consisting essentially of a metal, a plurality of inorganic particles, and a plurality of discrete fibers cannot further include additives, such as materials used to aid in the dispersion of such fillers.

根據本揭露之態樣的金屬基質複合物可根據具有通常知識之從業人士所知的各種適當方法製備,包括粉末冶金製程諸如熱壓、粉末擠製、熱軋、加熱隨之溫軋(warm rolling)、冷壓並燒結、以及熱等靜壓。在一實施例中,可藉由混合一金屬粉末、複數個無機粒子、及複數個不連續纖維以將該等無機粒子及不連續纖維分散在該金屬粉末中,隨之藉由燒結該混合物以形成一金屬基質複合物來形成該金屬基質複合物。例如,如此的一種粉末冶金方法係詳細說明於以下實例1中。 Metal matrix composites according to aspects of the present disclosure can be prepared according to various suitable methods known to those of ordinary skill in the art, including powder metallurgy processes such as hot pressing, powder extrusion, hot rolling, and heating followed by warm rolling. ), cold pressing and sintering, and hot isostatic pressing. In one embodiment, the inorganic particles and the discontinuous fibers may be dispersed in the metal powder by mixing a metal powder, a plurality of inorganic particles, and a plurality of discontinuous fibers, thereby sintering the mixture.
