摘　　要：研究了形变强化双相钢的低温冲击韧度。试验结果表明，形变强化双相钢经490℃回复90min后，低温冲击韧度显著改善。对试验数据进行了计算机拟合。The impact toughness of strain-strengthening dual-phase steel at low temperature was re searched. Experimental results show that after the recovery treatment at 490℃ for 90min,the impact toughness of strain-strengthening dual-phase steel at low temperature was improved obviously. The data of the experiment are processed by computer.

关 键 词：双相钢 形变 强化 回复 冲击 韧度
