摘　　要：测试50Mn中强钢880℃淬火不同温度回火后的力学性能,探讨断裂韧性JIC与V型缺口冲击功AKV和预裂纹冲击功AE之间的关系,认为JIC与AE之间有较好的线性关系。We test the mechanical property of 50Mn middle strength steel,which has been quenched at 880℃ and tempered at different temperature and discuss the relations between fracture toughness JIC and Charpy V-notch impact energy AKV,and the relations between fracture toughness JIC and cracking impact energy AE.The results show that JIC and AE have better linear correlation.

关 键 词：中强钢 断裂韧性 冲击功
