文摘

Inconel 718 superalloy was refined firstly by electron beam smelting. The mole fraction of Fe in Inconel 718 superalloy was found little change at different temperature. The relationship of Cr > Ni > Fe can be found for evaporation rates during experiments. The theoretical mass loss rates of Ni, Cr and Fe are in good agreement with the experiments.
