摘要
对比研究了不同C含量对高强生态钢板的显微组织、硬度、冲击性能、拉伸性能和磨损性能的影响。结果表明,随着C含量的增加,高强生态钢硬度呈现逐渐增加的趋势,冲击韧度呈现逐渐降低的趋势;随着C含量的逐渐增加,高强钢的抗拉强度逐渐上升,而断后伸长率和断面收缩率逐渐降低;在C含量为0.35%时,高强钢的抗拉强度、断后伸长率和断面收缩率分别为1 947 MPa、14.7%和26.4%;随着C含量的增加,加载载荷为5、15和25 kg时的磨损失重量都呈现为逐渐降低的趋势;C含量的增加使得高强钢的磨损失重逐渐降低,磨损机制从粘着磨损转变为切削磨损。
The effects of different C contents on the microstructure, hardness, impact performance, tensile properties and wear properties of high strength ecological steel were investigated. The results show that, with the increase of C content in high strength steel, the hardness increases gradually, the impact toughness decrease gradually, and the tensile strength gradually increase, while the elongation and contraction rate gradually decrease. When the content of C is 0.35%, the tensile strength, elongation and contraction rate of the high strength steel are 1 947 MPa, 14.7 % and 26.4 %, respectively. The wear loss of high strength steel with the load of 5, 15 and 25 kg is reduced gradually with the increase the C content, and the wear mechanism changes from adhesive wear to cutting wear.
