Abstract

The phase equilibria in the Ni-Al-Sn ternary system at 800 and 1000℃ was investigated by electron probe microanalysis and X-ray diffraction. The results show that: (1) No ternary compound is found at 800 and 1000℃. (2) The Ni-Al side presents four binary compounds including NiAl, Ni₃Al, Al₃Ni and Al₃Ni₂ phases. The solubilities of Sn in the binary NiAl and Ni₃Al phases are 3.1 at% and 14.7 at% at 800℃, and 3.0 at% and 8.0 at% at 1000℃, respectively. As for the binary Al₃Ni and Al₃Ni₂ phases, the solubilities of Sn are almost negligible. (3) The Ni-Sn side displays three binary compounds including Ni₃Sn(r), Ni₃Sn(h) and Ni₃Sn₂(h). The Ni₃Sn(r) phase is stable at 800℃ dissolving 4.2 at% Al, but it is replaced by the Ni₃Sn(h) phase with a 5.5 at% Al solubility at 1000℃. The solid solubility of Al in Ni₃Sn₂ (h) is 8.4 at% and 12.1 at% at 800 and 1000℃, respectively. (4) The Al-Sn side is occupied by an interconnected liquid region having only ~1 at% Ni solubility.
