Abstract

The effect of various pre-heat treatments (950~1150℃) on the surface and inside microstructure of the PREP FGH95 powder-particles has been studied.The results show that during pre-heat treatment,the microstructure of the powder particles may be more homogenized and the nonequilibrium carbides (MC') can be transformed into stable carbides(MC,M₂₃C₆,M₆C).
