摘要
选择幂级数模型描述了过剩自由能项,并从二、三元实测相图上用数据优化程序获得了所需热力学参数和交互作用系数,进而用多元相平衡计算法成功地预测了镍、钴,铬基合金中σ相的析出。
This paper try to predict the formation of o phase on the basis of thermodynamic equilibrium calculation. A power series model was chosed to express the excess free energy of multi-component non-ideal phase. All data including the interaction coefficient in binary and ternary alloy system were obtained by phase diagram fitting method. New method has the ability to predict phase formation correctly and enough precisely for all Ni-Co-Cr base sup-eralloys.
