摘　　要：基于AH36、EH36和FH500三种船体钢的梯度温度场型双重拉伸试验和落锤试验结果,对止裂温度和无塑性转变温度的相关性进行了分析。结果表明,三种船体钢止裂温度与无塑性转变温度之间存在一定的对应关系,反映了两种试验方法之间存在一定的相关性。Analysis was performed on correlation between crack arrest temperature and nil-ductility transition temperature of AH36,EH36 and FH500 ship steels based on experimental results of double tension test and drop weight test. Some relationship exists between crack arrest temperature and nil-ductility transition temperature for three steels,which reflecting the correlation between the two test methods.

关 键 词：止裂温度 无塑性转变温度 相关性
