Abstract:Through the analysis of the process and theoretical calculations for Ni and Mo elements during electron beam cold hearth melting, the element evaporation mechanism and kinetics of volatile were discussed. Single electron beam cold hearth melting technology of TA10 alloy was studied. The results show that the chemical compositions of the TA10 alloy ingot are uniform by electron beam cold hearth melting, the macro homogeneous is good, and the product meets the standards through the subsequent processing.
