摘要
The microstructure characteristics and microsegregation of DD2 single crystal have been studied under ultrahigh temperature gradient and rapid solidification conditions by laser rapid remelting. The experimental results show that the microstructure has been greatly refined after laser rapid remelting, the interdendritic precipitation phases have been remarkably suppressed and the microsegregation has been substantially improved.
