等温淬火热处理工艺对Fe-0.5C-2.0Si-2.5Mn钢冲击磨损性能的影响

Effect of Impact Wear on Isothermal Quenching of Fe-0.5C-2.0Si-2.5Mn Steel

  • 摘要: 采用MLD10动载磨粒磨损试验机对成分为Fe-0.5C-2.0Si-2.5Mn的贝氏体/马氏体复相钢进行冲击磨损试验, 通过观察磨损率, 表层组织演变以及表面磨损形貌的变化过程, 重点研究了等温淬火热处理工艺对Fe-0.5C-2.0Si-2.5Mn钢冲击磨损性能的影响, 结果表明: 经不同热处理后的贝氏体/马氏体复相钢的耐磨性较铸态有明显提高(1.4~2.3倍), 随着下贝氏体含量的增加, 耐磨性先降低再趋于平稳. 当冲击功由1 J增至4 J时, 材料磨损性能下降, 表面磨损形貌表征塑形破坏加剧; 当冲击功为5 J时, 组织中出现大量形变马氏体, 加工硬化明显, 表面磨损形貌较低能冲击下的表面更为平整均匀, 磨损性能增强, 但出现强烈的脆性断裂倾向.

     

    Abstract: Multiphase impact wear tests of a Fe-0.5C-2.0Si-2.5Mn bainitic / martensitic steel were conducted using an MLD 10 dynamic load abrasive wear testing machine. The wear rate, evolution of surface microstructure and worn surface were investigated, focusing on the isothermal quenching process on the impact wear properties. The results show that wear bainite / martensite phase steel complex than the cast has improved significantly (1.4 to 2.3 times), with the next increase bainite content, wear resistance was first reduced and then stabilized. When the impact energy by 1 J increased to 4 J, material wear decreased average, its worn surface characterization shaping aggravated damage. When the impact energy of 5 J, a large amount of deformation martensite appears tissue hardening significantly, worn surface under the impact of lower energy surface is more smooth uniform, wear resistance increased, but appear strong tendency to brittle fracture.
