10Cr9Mo1VNbN铁素体钢的动态断裂韧度
INSTRUMENTED IMPACT PROPERTIES AND DYNAMIC FRACTURE TOUGHNESS OF 10Cr9Mo1VNbN FERRITIC STEEL
【摘要】 采用标准夏比V型缺口试样的示波冲击试验获得了10Cr9Mo1VNbN钢的冲击特性和动态断裂韧度,对冲击过程进行了断裂力学分析,并检验了裂纹启裂能量、裂纹扩展能量、总冲击能量、动态断裂韧度之间的相关性。
【Abstract】 This paper reports the dynamic fracture toughness and impact properties of 10Cr9Mo1VNbN steel from CVN instrumented impact testing at a wide temperature range from -196 to 650 ℃.Experimental results from CVN impact test and dynamic fracture toughness determination are presented and discus sed. Correlations between CVN impact energy,dynamic fracture toughness are also examined.
