摘要：

The microstructure of liquid phase sintered M3:2 high speed steel and the effect of adding carbon and silicon on the microstructure was characterized by scanning electron microscopy, dispersive spectrometry, and X-ray diffraction. Various types of carbides were formed depending on the added carbon and/or silicon, the sintering atmosphere and the cooling rate. The microstructure of sintered M3:2 high speed steel samples in vacuum conditions without the addition of Si and graphite is composed mainly of MC and M 6 C carbides inside cells and primarily at cell boundaries. The M 2 C eutectic carbides in these samples were formed at cell boundaries and their amounts and morphology depends on the cooling rate. Sintered samples in N 2 atmosphere with added carbon and silicon, M 6 C eutectic and M 7 C 3 eutectic carbides were dominantly formed while carbonitrides were formed in smaller amounts.
