摘　　要：研究了热轧态Si-Mn双相钢的冲击韧度。试验结果表明，形变态螺栓的冲击韧度已基本符合GB3098．1－82的要求。经490℃回复90min后，冲击功达约120J，且拉断力符合GB3098．1-82的要求。对试验数据进行了计算机拟会。The impact toughness of the as-hot-rolled dual steel was studied in this paper. Experimental resultsshow that the impact toughness of the deformed bolt is qualified for the requirement of GB3098. 1-82. After therecovery at 490℃ for 90 min,the impact toughness can be reached 120J,or and the tensile force is still qualifiedfor the requirement of GB3098. 1-82. The data of the experiment are processed by computer.
