Abstract

The invention provides a particle-reinforced antiwear steel composite material, which comprises the following components in percentage by weight: 1 to 1.2 percent of C, 15 to 19 percent of Mn, 2 to 4 percent of V, 0.2 to 0.4 percent of Co, 0.02 to 0.05 percent of Si, 0.03 to 0.09 percent of Pr, 0.05 to 0.2 percent of Nd, 0.05 to 0.1 percent of Gd and the balance of Fe. The antiwear steel composite material is provided with fine and dispersed antiwear particles, so the composite material has the advantages of excellent common mechanical properties, improved tensile strength and impact toughness and high wear resistance. The invention also provides a method for preparing the particle-reinforced antiwear steel composite material. The method is simple and convenient. The particle-reinforced antiwear steel composite material prepared by the method also has the advantages of high properties, high integral strength, hardness and wear resistance, long service life, low production cost and convenient industrialized production.
