| Abstract: | Powder metallurgy M42 high speed steels(HSS)were prepared by the spark plasma sintering(SPS) technique.The effects of sintering process、heat treatment on microstructures and properties were studied.The results show that compared with traditional powder metallurgy high speed steels, the PM M42 high speed steels prepared by SPS technique have the uniform microstructure with fine grain size and no carbide segregation. The hardness of SPSed PM M42 HSS after quenching at 1180℃ and ternary multitempering at 550℃ for 1 hour heat treatment could be 1～2HRC higher than that of conventional sintered ones. |
| Keywords: | PM high speed steel M42 spark plasma sintering microstructures and performances |
