title = "Response of melt treatment on the solidified microstructure of Ti-48Al-2Cr-2Nb alloy",
abstract = "In this paper, the microstructure of Ti48A12Cr2Nb alloy after thermal cycling in the mushy zone was investigated. The results showed that the melt treatment has a significant effect on the grain size of the alloy. The lamellar colony was refined with the increasing time of thermal cycles. Further studies revealed that with the increasing of thermal cycling the dendrite morphology of Ti48A12Cr2Nb evolves as the following process: columnar →disfigured→ spheroidal. The remelting of dendrites during thermal cycling and the reinforced convection caused by electromagnetic stirring (EMS) were supposed to contribute to the refinement.",
