Abstract: Microstructure, mechanical properties and wear resistance of particle reinforced low-alloyed wear resistant steel tempered at different temperatures were studied. The results show that a large number of micron-scale and nanoscale TiC particles are uniformly dispersed in the rolled particle reinforced low-alloyed wear resistant steel. With the tempering temperature increasing, more ε-carbides are precipitated in the matrix, the yield strength of the tested steel overall increases first and then decreases, the tensile strength, hardness and impact absorbed energy gradually decrease, while the elongation gradually increases. The tested steel shows the best comprehensive mechanical properties and three-body abrasive wear properties when tempered at 200 ℃.

Key words: low-alloyed wear resistant steel, TiC particles, tempering treatment, abrasive wear, microstructure and properties
