Ni-Cr-Mo三元系1358 K等温截面的测定

Determination of the Isothermal Section of Ni-Cr-Mo Ternary System at 1358 K

摘要:

应用三元扩散偶技术测定了Ni-Cr-Mo三元系1358 K的等温截面,借助电子探针微区成分分析方法分析了Ni-Cr-Mo三元扩散偶的相区成分,并对其相关系进行了研究.测得Ni-Cr-Mo三元扩散偶在1358 K下存在一个中间化合物NiMo,Cr和Mo在扩散偶中形成连续固溶体,Ni和（Cr,Mo）有限固溶,扩散偶中未发现三元中间化合物.实验发现Ni-Cr-Mo三元系1358 K的等温截面存在一个三相区：Ni＋NiMo＋（Cr,Mo）.

Abstract:

The isothermal section of Ni-Cr-Mo ternary system at 1358 K was determined by means of diffusion triple and electron microprobe analysis. The results indicate that one binary intermetallic of NiMo is formed in Ni-Cr-Mo ternary system at 1358 K. In this diffusion triple, Cr and Mo formed into a continuous solid solution, and Ni and (Cr,Mo) formed into a finite solid solution. No ternary compound was observed. One three-phase region of Ni+NiMo+(Cr, Mo) exixts in the isothermal section of Ni-Cr-Mo ternary system at 1358 K.
