中文摘要:
      采用电子探针显微分析和X-ray衍射分析方法实验研究了Ni-Al-Sn三元体系在800°C和1000°C时的相平衡。结果表明:(1) Ni-Al-Sn三元体系在800°C和1000°C时均未发现三元化合物;(2) Ni-Al侧包含NiAl、Ni3Al、Al3Ni和Al3Ni2四个化合物,其中800°C时,Sn在NiAl和Ni3Al中的固溶度在分别为3.1和14.7 at.%,在1000°C时分别为3.0和8.0 at.%。而Sn在Al3Ni和Al3Ni2相中几乎没有固溶度;(3) Ni-Sn侧包含Ni3Sn(r)、Ni3Sn(h)和Ni3Sn2(h)三个化合物相。800°C时,Ni3Sn(r)相的固溶度为4.2 at.%,1000°C时,Ni3Sn(r)相转变为Ni3Sn(h)相,拥有5.5 at.% 的固溶度。另外,800°C时,Al在Ni3Sn2(h)相中的固溶度为8.4 at.%,1000°C时为12.1 at.%;(4) Ni-Al-Sn三元体系Al-Sn侧为相互贯通的液相区域,实验测得的Ni在Al-Sn侧的溶解度约为1 at.%。

英文摘要:
      The phase equilibria in the Ni-Al-Sn ternary system were investigated by means of electron probe microanalysis and X-ray diffraction. The experimental results showed that: (1) No ternary compound was found at 800°C and 1000°C. (2) The Ni-Al side presented four binary compounds included NiAl, Ni3Al, Al3Ni and Al3Ni2 phases. The solubilities of Sn in the binary NiAl and Ni3Al phases were determined as 3.1 at.% (Atomic ratio) and 14.7 at.% at 800°C, and 3.0 at.% and 8.0 at.% at 1000°C, respectively. As for the binary Al3Ni and Al3Ni2 phases, the solubilities of Sn were almost negligible. (3) The Ni-Sn side displayed three binary compounds included Ni3Sn(r), Ni3Sn(h) and Ni3Sn2(h). The Ni3Sn(r) phase was stable at 800°C dissolving 4.2 at.% Al but it was replaced by the Ni3Sn(h) phase with a 5.5 at.% Al solubility at 1000°C. The solid solubility of Al in Ni3Sn2(h) was 8.4 at.% and 12.1 at.% at 800°C and 1000°C respectively. (4) The Al-Sn side was occupied by an interconnected liquid region having only ~1 at.% Ni solubility.
