Abstract

Abstract

The microsegregation characteristic with which structure of rapidly solidified Powders of maraging steel is accompanied has been studied. The experimental results are as follows:with increasing cooling rates, segregation characteristic changed as the structure changed from dendritic→cellular-dendritic→cellular→pisolitic morphology. Microsegregation extent decreased obvious.It is found that nosegregation occurs when the microstructure is Pisolitic structure.
