摘要：
In recent years, multi-component alloys prepared by EB-PVD technology have been used in many fields. Kinetics and thermodynamics in evaporation of multi-component alloy are carried out for choosing better technological parameters to control the composition variation. Wilson equation and Miedema expanded model are applied to calculate the activity of each component, on basis of which a mathematical model is presented providing the change of the activity and the composition of the molten pool and vapor in dependence on the evaporation time and determining the transient time for vapor composition to reach a balance. A special Ni-Fe-Cr-Al alloy is fabricated by EB-PVD and the composition of molten pool and along thickness is measured. The calculated results are in agreement with experimental data.
