以下に、本発明の１つの好ましい実施態様を説明する。表１に示される組成を有する超合金が鋳造された。 In the following, one preferred embodiment of the present invention will be described. A superalloy having the composition shown in Table 1 was cast.
特に、該超合金はＮｉ、Ｃｏ、Ｃｒ、Ｍｏ、Ｗ、Ａｌ、Ｔａ、Ｈｆ、ＣおよびＢの元素を含み、且つ非常に特別にはそれらの元素のみからなる。 In particular, the superalloy contains the elements Ni, Co, Cr, Mo, W, Al, Ta, Hf, C and B, and very particularly consists solely of these elements.
表１の鋳造超合金の特性を特徴付けるために、種々の実験を実施した。 Various experiments were conducted to characterize the properties of the cast superalloys in Table 1.
４時間の溶解実験を４時間、１２２０、１２５０、１２６０、１２７０および１３００℃で行い、その後、水焼き入れを行った。１２２０℃で残留粒子が見られ、且つ１２５０、１２６０、１２７０および１３００℃で融解の前兆なく完全な溶解が観察された。 A 4 hour dissolution experiment was conducted for 4 hours at 1220, 1250, 1260, 1270 and 1300 ° C., followed by water quenching. Residual particles were seen at 1220 ° C. and complete dissolution was observed at 1250, 1260, 1270 and 1300 ° C. with no precursor of melting.
さらなる熱処理を１２５０℃で８時間、１１００℃で４時間、および８５０℃で２４時間適用した。ＳＥＭおよびＴＥＭ分析は、側長〜０．３５μｍの一次粒子を有する非常に規則的な微細構造および有意な量の二次粒子を示した（図１および２を参照）。 Further heat treatment was applied at 1250 ° C. for 8 hours, 1100 ° C. for 4 hours, and 850 ° C. for 24 hours. SEM and TEM analysis showed a very regular microstructure and a significant amount of secondary particles with side lengths of ~ 0.35 μm primary particles (see FIGS. 1 and 2).
わずかなＴＣＰ相も見られなかった。粒子含有率は〜６０容積％であると測定された。 A slight TCP phase was not observed. The particle content was measured to be ~ 60% by volume.
この比較的高い粒子含有率では、通常、前記の大きい熱処理ウィンドウを得ること、あるいは脆性相の析出なしで１４％ものＣｒを含むことは困難である。 At this relatively high particle content, it is usually difficult to obtain the large heat treatment window or to contain as much as 14% Cr without the precipitation of a brittle phase.
従って、Ｃｒ、ＴａおよびＡｌを中心に多くて中程度のレベルの他の合金元素とで、大きな熱処理ウィンドウおよび良好な微細構造の安定性が提供されることが示された。酸化耐性に対して、Ａｌが非常に有益、ＣｒおよびＴａが有益、ＭｏおよびＷが少し有害（且つＴｉ、ＮｂおよびＶが有害）であるとみなされるため、表１の組成物は高い酸化耐性を有するであろう。１４％のＣｒおよび低レベルの有害元素Ｍｏでは、それは高い腐食耐性も有するであろう。 Thus, it has been shown that a large heat treatment window and good microstructural stability are provided with other alloy elements at most to moderate levels, centered on Cr, Ta and Al. The compositions in Table 1 have high oxidation resistance because Al is very beneficial, Cr and Ta are beneficial, Mo and W are considered slightly harmful (and Ti, Nb and V are harmful) for oxidation resistance. Would have. With 14% Cr and low levels of the harmful element Mo, it will also have high corrosion resistance.
中程度のレベルのＭｏおよびＷで担持された１０％ものＴａを有する場合もまた高い強度を有する。なぜならＴａが非常に効力のある強化元素だからである。その結果、それは高強度、高酸化耐性、高腐食耐性、微細構造の安定性、および大きな熱処理ウィンドウにおける我々の要求を満たす。 It also has high strength with as much as 10% Ta supported on moderate levels of Mo and W. This is because Ta is a very effective strengthening element. As a result, it meets our demands on high strength, high oxidation resistance, high corrosion resistance, microstructure stability, and large heat treatment window.
表２は本発明のさらに好ましい実施態様を示す。 Table 2 shows further preferred embodiments of the present invention.
特に、該合金はＮｉ、Ｃｏ、Ｃｒ、Ｍｏ、Ｗ、Ａｌ、Ｔａ、Ｈｆ、Ｚｒ、ＣおよびＢの元素を含み、且つ非常に特別にはそれらの元素のみからなる。 In particular, the alloy contains the elements Ni, Co, Cr, Mo, W, Al, Ta, Hf, Zr, C and B, and very particularly consists solely of these elements.
最も高い酸化耐性合金、例えばＣＭＳＸ−４は＞５％のＡｌを含有し、且つ製造工程で鋳造されて＜５ｐｐｍのＳ、および最近では＜０．５ｐｐｍもの低いＳのレベルで得られる。 The highest oxidation resistant alloys, such as CMSX-4, contain> 5% Al and are cast in the manufacturing process to obtain <5 ppm S, and recently S levels as low as <0.5 ppm.
表２の組成物は、〜３０ｐｐｍであると見積もられる硫黄（Ｓ）の平均含有率を有し、その際、それは極めて有害であり、且つＡｌ含有率は比較的、中程度の４．５％である。 The composition of Table 2 has an average content of sulfur (S) estimated to be ˜30 ppm, where it is extremely detrimental and the Al content is relatively moderate 4.5% It is.
それにもかかわらず、表２の該合金における周期的な酸化試験は、１時間のサイクル時間および１１００℃の試験温度の厳しい試験条件の下で３００時間の安定した反応を示し、それは安定なアルミナを形成する能力、即ち高い酸化耐性を示す。従って、Ｃｒ、ＴａおよびＡｌを中心に多くて中程度のレベルの他の合金元素とで、高い酸化耐性が提供されることが示された。 Nevertheless, periodic oxidation tests on the alloys in Table 2 show a stable reaction of 300 hours under severe test conditions of 1 hour cycle time and 1100 ° C. test temperature, which shows stable alumina. It shows the ability to form, ie high oxidation resistance. Accordingly, it has been shown that high oxidation resistance is provided with other alloying elements having a medium and high level, mainly Cr, Ta and Al.
表２の組成物は表１の組成物よりも低い粒子含有率を有し、約６０容積％ではなく約４５容積％であり、従って、より大きい熱処理ウィンドウを有し、且つ、少なくとも安定なはずである。１６％のＣｒおよび低レベルの有害元素Ｍｏによって、それは高い腐食耐性も有する。 The composition of Table 2 has a lower particle content than the composition of Table 1 and is about 45% by volume instead of about 60% by volume, thus having a larger heat treatment window and at least stable. It is. With 16% Cr and a low level of the harmful element Mo, it also has a high corrosion resistance.
中程度のレベルのＭｏおよびＷで担持された１０％ものＴａによって、それは高い強度も有する。なぜならＴａが非常に効力のある強化元素だからである。 With as much as 10% Ta supported on moderate levels of Mo and W, it also has high strength. This is because Ta is a very effective strengthening element.
その結果、それは高強度、高酸化耐性、高腐食耐性、微細構造の安定性、および大きな熱処理ウィンドウにおける我々の要求を満たす。 As a result, it meets our demands on high strength, high oxidation resistance, high corrosion resistance, microstructure stability, and large heat treatment window.
