Correlation between Crack Arrest Temperature and Nil-ductility Transition Temperature |

| Abstract: | 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. |
