Description
Den foreliggende oppfinnelse vedrører silisiumbaserte, aluminium- og titaninneholdende legeringer og pulverbaserte produkter fremstilt av slike legeringer. Den foreliggende oppfinnelse vedrører videre en fremgangsmåte for fremstilling av silisiumbaserte, aluminium- og titaninneholdende legeringer, samt en fremgangsmåte for fremstilling av gjenstander fra slike legeringer. The present invention relates to silicon-based, aluminum- and titanium-containing alloys and powder-based products made from such alloys. The present invention further relates to a method for producing silicon-based, aluminum- and titanium-containing alloys, as well as a method for producing objects from such alloys.
Silisium er hittil idet alt vesentligste blitt benyttet som utgangsmateriale for fremstilling av silaner, produkter for elektroniske formål og som legeringsmiddel for stål og aluminium. For stål tilsettes silisium vanligvis i form av ferrosilisium i mengder som normalt er under 4 vekt % silisium. For aluminium og aluminiumlegeringer tilsettes silisium i form av elementært silisium. Innholdet av silisium i aluminiumlegeringer varierer sterkt, men kan for aluminiumsilisium legeringer innlegeres i mengder av maksimum 20 vekt % av legeringene. Silicon has so far mainly been used as a starting material for the production of silanes, products for electronic purposes and as an alloying agent for steel and aluminium. For steel, silicon is usually added in the form of ferrosilicon in amounts that are normally below 4% silicon by weight. For aluminum and aluminum alloys, silicon is added in the form of elemental silicon. The content of silicon in aluminum alloys varies greatly, but for aluminium-silicon alloys, quantities of a maximum of 20% by weight of the alloys can be incorporated.
Elementært silisium er meget sprøtt og mangler duktilitet. Videre fører tilsetning av silisium til f.eks. aluminiumlegeringer til økende sprøhet av legeringene når silisiuminnholdet overstiger ca. 20 vekt %. Så langt oppfinnerne kjenner til finnes det derfor idag ikke silisiumbaserte legeringer som har slike egenskaper at legeringene kan anvendes for konstruksjonsformål. Elemental silicon is very brittle and lacks ductility. Furthermore, the addition of silicon leads to e.g. aluminum alloys to increasing brittleness of the alloys when the silicon content exceeds approx. 20% by weight. As far as the inventors are aware, there are therefore no silicon-based alloys today that have such properties that the alloys can be used for construction purposes.
Silisium har imidlertid en rekke egenskaper som gjør at bruk av silisiumbaserte legeringer for konstruksjonsformål er meget interessant. Silisium har således en lav egenvekt på 2,3 og et høyt smeltepunkt på 1410°C. Silisiumbaserte legeringer med-tilstrekkelig duktilitet og styrke vil således kunne oppvise en rekke fordeler i forhold til andre lettmetaller så som for eksempel Al, Ti, Mg og Be. Spesielt gjelder det egenskaper som høy stivhet i forhold til egenvekt, anvendelse ved høyere temperaturer enn andre lettmetaller, lav varmeutvidelse, god korrosjonsmotstand og god erosjonsmotstand. I den etterfølgende tabell er en del egenskaper for silisium sammenlignet med egenskapene for Mg, Al, Ti og rustfritt 18/8 stål. However, silicon has a number of properties that make the use of silicon-based alloys for construction purposes very interesting. Silicon thus has a low specific gravity of 2.3 and a high melting point of 1410°C. Silicon-based alloys with sufficient ductility and strength will thus be able to show a number of advantages compared to other light metals such as Al, Ti, Mg and Be. In particular, this applies to properties such as high stiffness in relation to specific weight, use at higher temperatures than other light metals, low thermal expansion, good corrosion resistance and good erosion resistance. In the following table, some properties for silicon are compared with the properties for Mg, Al, Ti and stainless 18/8 steel.
Det er et formål ved den foreliggende oppfinnelse å fremskaffe silisiumbaserte legeringer med en slik duktilitet og styrke at legeringene kan anvendes for konstruksjonsformål. Samtidig som legeringene bibeholder silisiums gode egenskaper. It is an aim of the present invention to provide silicon-based alloys with such ductility and strength that the alloys can be used for construction purposes. At the same time, the alloys retain silicon's good properties.
Den foreliggende oppfinnelse vedrører således en hurtig størknet silisiumbasert legering, hvilken legering er kjennetegnet ved at den inneholder 2-40 vekt % Al, 2 - 45 vekt % Ti, 0 - 10 vekt % av ett eller flere av elementene V, Cr, Mn, Fe, Ni, Co, 0 - 1 vekt % av et eller flere av elementene B, Sr, P og rest silisium bortsett fra eventuelle forurensninger med den tilleggsbestemmelse at legeringen inneholder minst 35 vekt %Si. The present invention thus relates to a rapidly solidified silicon-based alloy, which alloy is characterized by the fact that it contains 2-40% by weight Al, 2-45% by weight Ti, 0-10% by weight of one or more of the elements V, Cr, Mn, Fe, Ni, Co, 0 - 1% by weight of one or more of the elements B, Sr, P and residual silicon, apart from any impurities with the additional provision that the alloy contains at least 35% Si by weight.
I henhold til en foretrukket utførelsesform inneholder silisiumlegeringen 10 - 30 vekt % Al og 3 - 15 vekt % Ti. According to a preferred embodiment, the silicon alloy contains 10-30% by weight Al and 3-15% by weight Ti.
I henhold til en ytterligere utførelsesform inneholder legeringen 2-10 vekt % Al og 25 - 40 vekt % Ti. According to a further embodiment, the alloy contains 2-10% by weight Al and 25-40% by weight Ti.
Legeringen i følgende oppfinnelse inneholder fortrinnsvis bor i en mengde av 0,01 - 0,1 vekt %, og/eller fosfor i en mengde av 0,01 - 0,05 vekt % og/eller strontium i en mengde av 0,05 - 0,5 vekt %. The alloy in the following invention preferably contains boron in an amount of 0.01 - 0.1% by weight, and/or phosphorus in an amount of 0.01 - 0.05% by weight and/or strontium in an amount of 0.05 - 0.5% by weight.
Elementene V, Cr, Mn, Fe, Ni og Co tilsettes fortrinnsvis i mengder av 1 - 3 vekt %. The elements V, Cr, Mn, Fe, Ni and Co are preferably added in amounts of 1 - 3% by weight.
Den størknede legering har fortrinnsvis en primær kornstørrelse mindre enn 50|im, og foretrukket mindre enn 10|j.m. For å oppnå best mulig styrke og duktilitet er det spesielt foretrukket at den størknede legering og de utskilte intermetalliske fasene har en primær kornstørrelse mindre enn l(im. The solidified alloy preferably has a primary grain size of less than 50 µm, and preferably less than 10 µm. In order to achieve the best possible strength and ductility, it is particularly preferred that the solidified alloy and the separated intermetallic phases have a primary grain size smaller than l(im.
Den foreliggende oppfinnelse vedrører videre en fremgangsmåte for fremstilling av en hurtig størknet silisiumbasert legering, hvilken fremgangsmåte er kjennetegnet ved at det tilveiebringes en smelte bestående av 2 - 40 vekt % Al, 2 - 45 vekt % Ti, 0 - 10 vekt % av ett eller flere av elementene V, Cr, Mn, Fe, Ni og Co, 0-1 vekt % av ett eller flere av elementene B, Sr, P og rest silisium bortsett fra eventuelle forurensninger, med den tilleggsbestemmelse at legeringen inneholder minst 35 vekt % Si, hvilken smelte størknes med en størkningshastighet av minst 10^ °C/sekund. The present invention further relates to a method for producing a rapidly solidified silicon-based alloy, which method is characterized by providing a melt consisting of 2 - 40% by weight Al, 2 - 45% by weight Ti, 0 - 10% by weight of one or several of the elements V, Cr, Mn, Fe, Ni and Co, 0-1% by weight of one or more of the elements B, Sr, P and residual silicon apart from any impurities, with the additional provision that the alloy contains at least 35% by weight Si , which melt solidifies at a solidification rate of at least 10^ °C/second.
I henhold til en foretrukket utførelsesform størknes smeiten med en størkningshastighet mellom 10^ og 10^ °C/sekund. According to a preferred embodiment, the melt is solidified at a solidification rate between 10^ and 10^ °C/second.
Størkningen foretas fortrinnsvis ved hjelp av smeltespinning eller ved hjelp av gassatomisering. Det ligger imidlertid innenfor rammen av den foreliggende oppfinnelse å anvende andre kjente metoder for å oppnå en tilstrekkelig høy størkningshastighet. The solidification is preferably carried out by means of melt spinning or by means of gas atomisation. However, it is within the scope of the present invention to use other known methods to achieve a sufficiently high solidification rate.
Den foreliggende oppfinnelse vedrører videre en fremgangsmåte for fremstilling av konsoliderte produkter fra hurtig størknede silisiumbaserte legeringer, hvilken fremgangsmåte er kjennetegnet ved at hurtig størknede silisiumbaserte legeringer bestående av 2 - 40 vekt % Al, 2 - 45 vekt % Ti, 0 - 10 vekt % av ett eller flere av elementene V, Cr, Mn, Fe, Ni, Co, 0-1 vekt % av ett eller flere av elementene B, Sr og P og rest silisium bortsett fra vanlige forurensninger, med den tilleggsbestemmelse at legeringen inneholder minst 35 vekt % Si, knuses og males til en partikkelstørrelse mindre enn 500(im og formes til gjenstander ved pulvermetallurgiske prosesser, hvoretter de formede gjenstander varmkonsolideres. The present invention further relates to a method for the production of consolidated products from rapidly solidified silicon-based alloys, which method is characterized by rapidly solidified silicon-based alloys consisting of 2 - 40% by weight Al, 2 - 45% by weight Ti, 0 - 10% by weight of one or more of the elements V, Cr, Mn, Fe, Ni, Co, 0-1% by weight of one or more of the elements B, Sr and P and residual silicon apart from common impurities, with the additional provision that the alloy contains at least 35% by weight % Si, is crushed and ground to a particle size of less than 500 (im and shaped into objects by powder metallurgical processes, after which the shaped objects are heat consolidated.
I henhold til en foretrukket utførelsesform males den hurtig størknede silisiumbaserte legering til en partikkelstørrelse mindre enn 200|im før gjenstandene formes. According to a preferred embodiment, the rapidly solidified silicon-based alloy is milled to a particle size of less than 200 µm before forming the articles.
Forming av gjenstander og konsolidering av de formede gjenstandene utføres ved hjelp av kjente pulvermetallurgiske prosesser. Det foretrekkes å benytte varm isostatisk pressing, men det ligger innenfor rammen av oppfinnelsen å benytte metoder så som for eksempel kald isostatisk pressing etterfulgt av sintring, varm enakset pressing, smiing, ekstrudering og injeksjonsstøping etterfulgt av sintring. Shaping of objects and consolidation of the shaped objects is carried out using known powder metallurgical processes. It is preferred to use hot isostatic pressing, but it is within the scope of the invention to use methods such as, for example, cold isostatic pressing followed by sintering, hot uniaxial pressing, forging, extrusion and injection molding followed by sintering.
Det har overraskende vist seg at konsoliderte produkter av den silisiumbaserte legering i henhold til den foreliggende oppfinnelse har en meget høy kompresjonsstyrke og en tilstrekkelig duktilitet til at legeringsproduktene kan anvendes for konstruksjonsformål. It has surprisingly been found that consolidated products of the silicon-based alloy according to the present invention have a very high compressive strength and a sufficient ductility for the alloy products to be used for construction purposes.
Ved hurtigstørkning av de silisiumbaserte legeringene i henhold til den foreliggende oppfinnelse oppnås det et svært finkornet materiale som spesielt er karakterisert ved en eksepsjonell finfordeling av de intermetalliske fasene i materialet og dertil hørende stor tetthet av korngrenser. Det antas at det er denne kombinasjonen som gir materialet dets duktilitet og styrke i henhold til oppfinnelsen. Ved varmkonsolideringen av gjenstandene i henhold til den foreliggende oppfinnelse er det viktig å velge temperatur og trykkforløp slik at materialet blir tilstrekkelig tett og at kornveksten under konsolideringen ikke forringer materialets egenskaper. By rapid solidification of the silicon-based alloys according to the present invention, a very fine-grained material is obtained which is particularly characterized by an exceptionally fine distribution of the intermetallic phases in the material and the associated high density of grain boundaries. It is believed that it is this combination that gives the material its ductility and strength according to the invention. During the hot consolidation of the objects according to the present invention, it is important to choose the temperature and pressure sequence so that the material becomes sufficiently dense and that grain growth during consolidation does not impair the material's properties.
EKSEMPEL 1 EXAMPLE 1
En silisiumlegering inneholdende 25 vekt % Al, 5 vekt % Ti og rest silisium bortsett fra vanlige forurensninger, ble smeltet i en vakuum ovn og støpt ut til en stang. Stangen ble benyttet som utgangsmateriale for smeltespinning. Ved smeltespinningen ble legering smeltet og størknet til tynne folier eller ribbons med en størkningshastighet på over 10^ °C/sekund. A silicon alloy containing 25 wt% Al, 5 wt% Ti and residual silicon apart from common impurities was melted in a vacuum furnace and cast into a bar. The bar was used as starting material for melt spinning. During melt spinning, alloy was melted and solidified into thin foils or ribbons with a solidification rate of over 10^ °C/second.
Foliene ble malt i en lukket mølle til en partikkelstørrelse mindre enn 200|im. The foils were ground in a closed mill to a particle size of less than 200 µm.
Legeringspartiklene ble deretter fylt i en sylinderformet matrise med en diameter på 1 cm og en høyde av mer enn 1 cm. Deretter ble legeringspartiklene presset ved et enakset trykk på 40 MPa og ved en temperatur av 700°C i to timer. The alloy particles were then filled into a cylindrical matrix with a diameter of 1 cm and a height of more than 1 cm. Then, the alloy particles were pressed at a uniaxial pressure of 40 MPa and at a temperature of 700°C for two hours.
De produserte gjenstander ble deretter testet ved kompresjonstesting. Bruddstyrken ble målt til 878 MPa og en lengdeforandring ved kompresjon til brudd på 7 %. The manufactured items were then tested by compression testing. The breaking strength was measured at 878 MPa and a length change in compression to break of 7%.
Resultatene viser at fremstilte legeringer har en meget høy kompresjonsstyrke og en kompresjonslengde som er i paritet med fiberforsterket aluminium. The results show that the produced alloys have a very high compressive strength and a compression length that is on a par with fibre-reinforced aluminium.
