The microstructure characteristics and microsegregation of DD2 single crystal have been studied under ultra-high 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, interdendritic precipitation phases remarkably suppressed and the microsegregation substantially improved.
