| 摘 要： | 采用带有不同拘束条件的热模拟方法研究了９％Ｎｉ钢多道焊热影响区的韧性变化。着重讨论“逆转”奥氏体及“遗传”现象的产生条件及其影响。认为；对于保证９％Ｎｉ钢焊接热影响区的韧性而言，采用多道焊工艺是合理的，应力求有适当的回火热循环的作用。

| Abstract: | The change in toughness in multipass weld HAZ of 9%Ni steel was studied by multi-thermal-cycle simulation under different restraint conditions. The conditions of generation of "reverse" austenite and of the "heredity" phenomenon are discussed. It is desirable that multioass weld thermal cycle should be applied, which gives significant tempering effect for improvement of law-temperature toughness. |
