摘要
对工业上常用的30CrMnSi钢进行了几种实用的,易于推广的强韧化工艺试验,并对它们的强韧性作了对比,对显微组织和冲击断口进行了观察。找出了30CrMnSi钢较理想的强韧化方法,称之为“高强韧化”方法。
This paper conducts tests on toughening technique for 30CrMnSi steel ,and compares the ductility. Themicrostructure as well as impact fracture is observed. An ideal toughening technique is found for 30CrMnSi steel
