摘要
本文通过低温系列拉伸、冲击的实验方法,对环境低温下60Si_2Mn的机械性能进行了研究。试验表明:经870℃奥氏体化加310％等温淬火,再经300℃回火的60Si_2Mn弹簧钢具有良好的强韧性配合。
The low temperature properties of 60Si2Mn steel have been studied through low temperature series tension and impact experiments. The results denote that the 60Si2Mn steel austenitized at 870℃, martempered at 310 ℃ and temperture at 300 ℃ shows a good matching of strength and toughness.
