摘要
分析研究了Ｊ积分测试过程中的一些现象，发现Ｊ积分中陡降载荷对应的脆性转变温度和落锤及冲击脆性转变温度有很好的一致性。快速断裂能量与冲击断裂能量有较好的一致性。
Some experimental phenomena in J integration testing were analyzed, and it was found that the Nil Ductility Transition Temperature determined by the load drop of J integration has a good correspondence with one determined by NRL-drop weight test and Charpy impact test, the energy of fast fracture conforms to the Charpy impact energy.
