Through a series of quenching, tempering, tensile testing, low-temperature impact test and metallographic analysis, we ultimately came to the following conclusions:(1) low-carbon alloyed steel 20CrMn2NiMoV quenching at 870℃ and tempering at 200℃, whose structure contains tempered dislocation lath martensite and few small bainite under mixed, has the best obdurability;(2) Carbon Steel 45CrMn2NiMoV quenching at 850℃ and tempering at 620℃, whose structure is sorbitic, has a performance less than that of low-carbon Alloyed steel, but it can also meet the basic design requirements.(3) Mn can substitute for the role of Ni within limited extent.
通过一系列淬火、回火、拉伸试验、低温冲击试验以及金相分析,最终得出以下主要结论:(1)低碳合金钢20CrMn2NiMoV经870℃淬火+200℃回火,得到回火位错型板条马氏体+少量细小下贝氏体的混合组织,具有最佳的强韧性配合;(2)中碳合金钢45CrMn2NiMoV经850℃淬火+620℃回火,得到回火索氏体组织,综合性能虽然不及低碳合金钢,但也能基本满足设计要求;(3)Mn在一定程度上能够替代Ni的作用,适量的Mn和Ni相互配合可以得到最佳的低温韧性,因此&以Mn代Ni&是低温钢材料研究开发中一条可行的适合我国资源状况的合金化思路。
