摘要
本文设计了多元超合金中液相,fcc,bcc和hcp四种溶体相的摩尔自由能及其活度的软件系统,其中包括一个复盖18种元素的二元合金热力学数据库。使用时,用户只要输入合金相的成分,相结构和温度,即可得到所需的计算结果。
A computer program,which includes a thermodynamic data base for binary
systems covering 18 chemical elements,has been developed to calculate the free
energies of the liquid,fcc,bcc,and hcp phases,and the partial free energies and
activities of the elements in the four phases in the multicomponent superalloys.The
program can be used to investigate the corrosion behavior of the multicomponent
alloys,predict the undercooling condition for the occurrence of metastable phases
in the alloys,or determine the carbon potentials of the alloys to be carburized.
