淬火分配工艺对60Si2Mn弹簧钢显微组织和力学性能的影响
Effect of Quenching and Partitioning Process on Microstructure and Mechanical Properties of 60Si2Mn Spring Steel
摘 要
对60Si2Mn弹簧钢进行了不同淬火温度（140，160，180℃）的淬火分配（Q&P）处理，研究Q&P处理后该钢的显微组织和力学性能，并与传统淬火+回火（Q&T）工艺处理后的进行对比。结果表明：经Q&P处理后，60Si2Mn弹簧钢的显微组织均为残余奥氏体和马氏体，残余奥氏体的体积分数均大于12%，而经Q&T处理后的显微组织主要为回火屈氏体/回火索氏体；随着淬火温度的升高，Q&P处理后该钢的强度、硬度降低，断后伸长率、冲击功、强塑积增大，并且均明显高于Q&T处理后的；在变形过程中残余奥氏体相变诱导塑性效应导致Q&P处理后弹簧钢的综合性能优于Q&T处理后的。

Abstract
60Si2Mn spring steel was treated by quenching and partitioning (Q&P) at different quenching temperatures (140,160,180 ℃). The microstructure and mechanical properties of the steel after Q&P treatment were investigated, and compared with those after traditional quenching and tempering (Q&T) treatment. The results show that the microstructure of 60Si2Mn spring steel after Q&P treatment consisted of retained austenite and martensite, and the volume fraction of retained austenite was more than 12%. The microstructure of the steel after Q&T treatment was tempered troostite/tempered sorbite. The strength and hardness of the steel after Q&P treatment decreased with increasing quenching temperature, and the percentage elongation after fracture, impact energy and product of strength and elongation increased, which were all larger than those after Q&T treatment. The comprehensive performance of the spring steel after Q&P treatment was better than that after Q&T treatment because of the transformation-induced plasticity effect caused by the restained austenite during deformation.
