15MnTi 钢的中子辐照效应

Neutron Irradiation Effect on 15MnTi Steels

介绍了１５ＭｎＴｉ钢的母材、焊缝及其热影响区在不同注量的快中子辐照后、材料的机械性能变化情况。根据试验结果得到，辐照温度为５０℃，快中子注量在１．０×１０１８ｃｍ－２到６．０×１０１８ｃｍ－２之间，１５ＭｎＴｉ钢的脆性转变温度增量ΔＴｃｖ与积分快中子注量的经验关系公式。

This article introduces changes of the mechanical properties for basic material,welding and heat affected zone of 15MnTi steels irradiated by different fast Neutron fluence.According to the test results,an empirical relation between the increment ΔTCV of the embrittlement temperature of the 15MnTi steels and the fast neutron fluence can be obtained under irradiation temperature at 50℃ and fast neutron fluence from 1.0×10 18cm-2 to 6.0×10 18cm-2.
