Y-Co-Ni三元系1000℃恒温截面的实验研究

Experimental Study of 1000℃ Isothemial Section of Y-Co-Ni System

摘要: 本文采用由纯金属组成的和由稀土与Co-Ni合金组成的两类扩散偶,辅以电子探针、金相、SEM等手段测定了Y-Co-Ni三元相图1000℃恒温截面上的相关系。该截面固相区范围内存在8个单相区、10个两相区、3个三相区。

Abstract: The isothermal section of Y-Co-Ni ternary system at 1000℃ was determined by diffusion couple and electron microprobe techniques, supplemented by optical microscopy, scanning electron microscopy. Considering only solid phase regions, this section consists of eight single-phase, ten two-phase, and three three-phase regions.
