system molten metal were calculated. A model for calculating the activity and activity coefficient of the molten ternary system alloys was derived based on Miedema’s model to calculate the formation heat of binary alloys, and Toop’s equation to calculate the excess free energy of ternary system solution. The activity coefficient and evaporation rate of the elements in Ti-6Al-4V alloy were also......
