Abstract

The prediction of thermodynamic properties of alloy melts in multi-element systems based on Molecular Interaction Volume Modeling (MIVM) requires only the basic physical parameters of the alloying elements to be passed, while simplifying the calculation process. In this paper, the algorithm is used to calculate the activity coefficients of the melt members of Ti-5Al-2.5Sn and Ti-0.3Mo-0.8Ni alloys and the calculated values agree with the experimental values. The activity coefficients of each member of the Ti-0.3Mo-0.8Ni-2Al-1Zr alloy melt was predicted. According to the volatilization model, the volatilization trend of each element in the process of Electron Beam Cold Hearth Melting (EBCHM) polyhedral alloy TA10 (Ti-0.3Mo-0.8Ni-2Al-1Zr) was predicted, and the accuracy of the theoretical model was verified by melting experiments.
