A detailed thermomagnetic analysis was carried out on a number of alloys along a tie-line in the two-phase (β+β') region of the Fe-Ni-Al ternary system. The supersaturated solid solution, obtained by quenching an alloy close to the composition Fe2NiAl, broke up very fast at relatively high temperatures ( ~ 850℃), precipitation being completed in a little more than a minute. The β' phase formed at 850℃ still contained about 35 at. % iron, with a Curie point near 400℃. When this alloy, after going through such...

A detailed thermomagnetic analysis was carried out on a number of alloys along a tie-line in the two-phase (β+β') region of the Fe-Ni-Al ternary system. The supersaturated solid solution, obtained by quenching an alloy close to the composition Fe2NiAl, broke up very fast at relatively high temperatures ( ~ 850℃), precipitation being completed in a little more than a minute. The β' phase formed at 850℃ still contained about 35 at. % iron, with a Curie point near 400℃. When this alloy, after going through such a short tempering at 850℃ followed by quenching, was heated up to 600-700℃ again, the β' phase formed during the first tempering continued to decompose rapidly, losing enough iron to become nonmagnetic in not much more than ten minutes. This caused the room-temperature coercive force of the alloy to rise to about 500 Oe. Such a phenomenon is in agreement with БгЛнвиЦ'S. г. suggestion of "post-precipitation". The magnetic measurements showed, moreover, that the post-precipitatioa of the β' phase was "reversible", that is, when the alloy was brought up to 850℃ again after quenching from the second tempering at 600-700℃, theβ' phase could recover its equilibrium composition for 850℃ in a few minutes. Decomposition of the supersaturated solid solution FejNiAl at relatively low temperatures (below 700℃) was quite slow, and, furthermore, there was considerable evidence that the process was "non-uniform". On the basis of the above findings, the fact that high coercive force in the alloy FeaNiAl cannot be obtained by quenching from above the solution temperature plus tempering at relatively low temperatures (600-700℃) is interpreted in the light of the single-domain particle theory.

用热磁分析方法较仔细地观测了Fe-Ni-Al三元系合金沿β+β′两相区内某一结线上的几个不同成分的合金样品。淬火所得的成分接近Fe_2NiAl的过饱和固溶体在较高温度(~850℃)分解甚快,在一分钟内脱溶基本上完成。在850℃分出的β′相还含铁约35at.%,其居里点在400℃附近。在850℃经短时间回火继以水淬的合金,在600—700℃再经适当的回火,则首次回火所生成的β′相继续迅速分解,在不超过十分钟内损失大量的铁而变成非铁磁性的;其在室温的H_c可增到500奥斯特。这和Б.Г.Лившнц“所提出的继续脱溶”的假设相符。磁性观测的结果证明:β′相的继续脱溶是“可逆的”,就是说,把曾在600—700℃回火的合金重热至850℃时β′相能在几分钟内恢复850℃的平衡成分。Fe_2NiAl过饱和固溶体在较低温度(70O℃以下)分解极慢,并且其过程是明显地“不均匀”的。因此,这种合金不能通过高温淬火继以较低温度(600—700℃)回火的处理来获得高H_c的事实可以用单畴粒子的理论加以解释。

Addition of Hf to a superalloy is one of the effective approaches to improve its mid-temperature properties. Based on R-alloy the apparent variations of the microstructure and phase composition in the alloy after addition of Hf were studied. As a result, in Hf-bearing alloy nearly 90% of Hf were dissolved into γ' phase, the rest were dissolved into the carbides and formed a small amount of Ni5Hf phase, and a trace of Hf went into the alloy matrix. As a result of dissolution of large quantity of Hf into γ' phase,...

Addition of Hf to a superalloy is one of the effective approaches to improve its mid-temperature properties. Based on R-alloy the apparent variations of the microstructure and phase composition in the alloy after addition of Hf were studied. As a result, in Hf-bearing alloy nearly 90% of Hf were dissolved into γ' phase, the rest were dissolved into the carbides and formed a small amount of Ni5Hf phase, and a trace of Hf went into the alloy matrix. As a result of dissolution of large quantity of Hf into γ' phase, the amount of γ' phase (including γ'+γ eu-tectic phase) increased from 62 wt%(R-alloy) to 64 wt%(1.5%Hf RH-alloy, the solution temperature of γ' phase increased by about 40℃, and the high temperature mi-crohardness of RH-alloy was obviously higher than R-alloy. As Hf was concentrated in the interdendrite region, the amount of the (γ'+γ) eutectic increased from 8 vol% (R-alloy) to 18 vol% (RH-alloy), therefore, the increase of eutectic (γ'+γ) contributed virtually to the increase of v'.Addition of Hf caused the morphology of the MC and M3B2 to convert from the forms of "script" or skeleton to those of plate or block and the solidusliquidus of the alloy to lower and the mushy region to broaden by approximately 10℃.

添加铪是改善合金中温性能的有效途径之一。本文在R合金基础上研究了加铪后合金中显微组织和相组成发生的明显变化。合金中约有90%的铪溶入γ′相中,其余溶入碳化物及形成少量的Ni_5Hf相,而在基体中溶入甚微。铪大量进入γ′中,使γ′〔(包括共晶(γ+γ′)〕数量增加,从未加铪的R合金的62wt%,增至加铪的R_H合金的64wt%,提高了γ′固溶温度约40℃,高温显微硬度明显的高于不加铪的R合金。由于铪富集于枝晶间,使共晶(γ+γ′)数量从R合金的8vol%增至R_H的18vol%,所以γ′数量的增加实际上是共晶(γ+γ′)数量的增加。铪的加入使MC和M_3B_2,形态从“草书体”或骨架状向块状或条状转变;降低了固液相线,扩大了两相区约10℃。

The directionally solidified (DS) superalloy DZ-22 possesses rather high mechanical properties at both intermediate and high temperatures, for instance, its stress-rupture strength for 100h at 760℃ and 1040℃ are 804MPaand 139MPa, respectively. Its properties are comparable with the well-known DS superalloy PWA1422. Therefore, it is applicable to advanced aircraft engine blades. The chemical composition of DZ-22 is based on the composition of PWA1422, but the content ranges of Hafnium and Carbon have been readjusted...

The directionally solidified (DS) superalloy DZ-22 possesses rather high mechanical properties at both intermediate and high temperatures, for instance, its stress-rupture strength for 100h at 760℃ and 1040℃ are 804MPaand 139MPa, respectively. Its properties are comparable with the well-known DS superalloy PWA1422. Therefore, it is applicable to advanced aircraft engine blades. The chemical composition of DZ-22 is based on the composition of PWA1422, but the content ranges of Hafnium and Carbon have been readjusted according to experimental results, so its Hafnium content is limited in 1.2-2.0 wt.% instead of 1.5-2.5 wt. % and its Carbon content is 0.12-0.16wt. % rather than 0.08-0.14 wt.%>. In addition, no Zirconium is added intentionally in the alloy. The test results show that the shell-mould with drawn rate during the DS process affects obviously on the orientation of columnar crystals. The suitable drawn rate has been established about 7 mm/min in the equipment of the present work. Enhancement of solution temperature during heat treatment can improve stress-rupture life at both 980℃ and 1040℃, while the elongation decreases slightly. A pretreatment at 1150℃ prior to the solution treatment can raise the incipient melting temperature.

定向凝固高温合金DZ-22具有较高的中、高温性能,与定向合金PWA1422相当,可用作航空发动机的涡轮叶片材料。它是以PWA1422合金的成分为基础,通过试验对其中铪、碳的含量作了调整。在定向凝固过程中铸型移动速度对零件柱晶的结晶取向有较大的影响。提高固溶处理温度,可明显提高合金的高温持久寿命,但延伸率稍有降低。在固溶处理前进行一次1150℃的预处理,可提高合金的初熔温度。
