摘要
应用多元扩散偶－电子探针微区成分分析技术，测定了Ｔｉ－Ｎｉ－Ｎｂ三元系相图的７００，８００，９００℃等温截面含镍量（原子分数）为０～５０％的大部分区域．完整地测定了α－Ｔｉ，β（Ｔｉ，Ｎｂ）及Ｔｉ２Ｎｉ的相区范围及相平衡关系。
ost of isothermal sections of the phase diagrams of Ti-Ni-Nb ternary system in which thenickel contents may be up to 50 at% Ni,were determined at 700,800 and 900℃ respectively,using diffusioncouple technique. The composition ranges and phase equilibrium relationships of Q--Ti,&(Ti,Nb)and TiZNiwere determined completely. A ternary compound Xo with possible stoichiometrical composition of Ti,Ni,Nb,is discovered for the first time.'
