摘　　要：使用纯Ti粉和纯Ag块压制紧密接触的Ag-Ti二元扩散偶,在980,1100和1200℃下分别进行退火处理.通过金相观察和电子探针微区分析,对退火处理后的试样进行相分析和成分测定,从而获得了相应温度下的Ag-Ti二元体系的相平衡关系和共轭平衡成分.特别是针对液相、β(Ti)相和(TiAg)中间相,将实验所得的结果与文献报道的评估数据进行了比较.The Ag-Ti diffusion couples were prepared by small pure silver plate closely packed in pure titanium powder and annealed at 980, 1100 and 1200℃respectively. The phase equilibrium relationship and the equilibrium composition of conjugate phases in Ag-Ti system were determined by means of metallographic microscope and electron probe microanalysis. Especially for the liquid phase the β(Ti) phase and the intermediated phase (TiAg). The experimental results of the present work were compared with the assessed data of the anailable literature.
