摘要
对20MnSi螺纹钢筋淬火后进行不同温度回火.通过冲击试验研究20MnSi螺纹钢筋第二类回火脆性产生的温度.试验确认20MnSi螺纹钢筋的第二类回火脆性产生温度在570～580℃.
The charpy impact test (U-notch) of 20MnSi steel bars after different heat treatment has been car-ried out. The relationship between impact toughness and tempering temperature indicated secondary tempering brit-tleness peak at between 570-580℃.
