Abstract：
A wear-resisting steel was taken as the research object, the microstructure of wear-resistant steel was investigated by SEM and TEM. The results show that the martensite matrix is narrow and the size of Cr23C6 carbide is small and the quantity is large. Part of Cr23C6 is dispersed in the grain, which plays the role of dispersion enhancement. It not only improves the hardness, but also improves the impact toughness.
