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７００℃等温截面，确定了该三元系相图的７００℃等温截面的１２个单相区、２３个两相区和１０个三相区。１２个单相区是：α－Ｔｉ、β－（Ｔｉ，Ｎｂ）、Ｔｉ_２Ｎｉ、ＴｉＮｉ、ＴｉＮｉ_３、（Ｎｉ）、Ｎｉ_３Ｎｂ、Ｎｉ_６Ｎｂ_７、Ｘ_Ａ、Ｘ_Ｂ、Ｘ_Ｃ和Ｘ_Ｄ，其中Ｘ_Ｂ化合物为首次发现。
The 700℃ isothermal section of the Ti-Ni-Nb ternary system was determined by means of the diffusion couple technique. 12 single-phase regions, 23 two-phase regions and 10 three-phase regions in this isothermal section were determined. The 12 single-phase regions include α-Ti solid solution, β-(Ti, Nb) solid solution,Ti_2Ni, TiNi, TiNi_3, fcc-(Ni) solid solution, Ni_3Nb, Ni_6Nb_7, X_A, X_B, X_C and X_D. The ternary compound X_B is discovered for the first time.
