The solidification structures and segregation of the VAR cast ingot of Ti-6Al-6V-2Sn alloy were investigated by using a new etching technique with a high concentration of hydrofluoric acid. Segregation of Fe and Cu is remarkable in the zone of equiaxed grains in the center of ingot. To minimize segregation, the authors propose a VAR procedure of casting at a faster solidification rate and a greater temperature gradient by the use of a consumable electrode tapered to the stick during hot topping.
