| 摘 要： | 研究了不同回火温度下颗粒强化型低合金耐磨钢的微观组织、力学性能和耐磨性能,确定了最佳的回火工艺。结果表明,轧制态颗粒强化型低合金耐磨钢中均匀弥散分布着大量微米级和纳米级TiC析出。回火温度升高,基体中ε-碳化物增多,试验钢的屈服强度整体上先升高后降低,抗拉强度、硬度和冲击吸收能量逐渐降低,伸长率逐渐升高,在200 ℃低温回火时,试验钢表现出最优的综合力学性能,同时表现出最佳的三体磨料磨损性能。

| 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 ℃. |
