Abstract

The effects of melting current and magnetic field in vacuum consumable arc remelting (VAR) process on the macrosegregation of Ti-10V-2Fe-3Al ingot are investigated in this paper. The results show that Fe content increases gradually from the bottom to the top of ingots along axial direction and the degree of macrosegregation is greater in the radial direction in the middle of the ingot versus the top and bottom. The macrosegregation rate of Fe element is higher with melting current of 2.6 kA than that of 1.7 kA in Ti-10V-2Al-3Fe ingot. There are two forces, buoyancy and Lorentz forces which arise from the flow of current through the pool of VAR when without magnetic stirring, but a new Lorentz force arising from the presence of external inductors occurs with adding magnetic stirring which decreases the macrosegregation rate of Fe element in Ti-10V-2Fe-3Al.
