5.Thermodynamic Investigation on the Liquid Sintering of the Refractory Mo Alloys

Abstract:Using CALPHAD method,the phase diagrams of the Cu-Ni,Cu-Mo and Mo-Ni binary systems were calculated by employing the thermodynamic database in literature.Through extrapolation from the relative binary systems,the isothermal section of Mo-Ni-Cu ternary system at 1273K was calculated.It is found that there is a narrow liquid phase area at the Mo-rich side,which demonstrates the possibility of liquid phase sintering at 1273K with some amount of addition of Cu and Ni.Furthermore,necessary experiment was carried out to cinfirm the calculation results.

钼合金耐火材料液相烧结性能热力学研究
摘要：利用文献已有的体系热力学数据，采用计算材料科学的方法计算了Cu-Ni、Cu-Mo、Ni-Mo3个二元体系相图，并热力学外退了Mo-Ni-Cu三元体系1273K等温截面图，发现在富Mo角存在一个狭小的液相区，表明在1273K的温度小已通过添加适量的铜镍固溶液可改善Mo合金的液相烧结性能，并实验验证了计算结果。
