Abstract

Relationship between melting velocity and electron beam power was determined by calculating thermal balance during melting TC4 alloy by electron beam cold hearth.An mathematical model was established to describe volatilization kinetics of Al element in TC4 alloy

and final Al content in the ingot at different melting parameters including melting velocity

Al content in initial raw materials was calculated by the model.The simulated results are well in agreement with experimental ones

verifying the reliability of the model.
