Abstract

Abstract

Use SEM, white dot precipipitations are found on the surface of rapid solidification powder of maraging steel after 3h aging at 480℃. The precipitations mainly distribute between the solidification dendrite arms on the surface, but none in the powders. The precipitations are the compound of Ti by using energy spectrum and wave spectrum analysis. The aging hardness of rapid solidification powders is much higher than that of solid quenching samples.
