摘　　要：研究了热轧态Ｓｉ－Ｍｎ双相钢的低温冲击韧度。试验结果表明热轧态Ｓｉ－Ｍｎ双相钢经４９０℃回复９０ｍｉｎ后，低温冲击韧度显著提高。The impact toughness of as-hot-rolled Si-Mn dual-phase steel at low temperature was researched. Experimental results show that after recovery treatment at 490℃ for 90min,the impact toughness of as -hot-rolled Si-Mn dual-phase steel at low temperature was improved obviously.

关 键 词：热轧态 双相钢 冲击 韧度 回复处理 低温
