Point defect behaviors during incubation period of void swelling in austenitic stainless steels

为了研究决定奥氏体不锈钢孔洞膨胀潜伏期的因素，用电子和中子对镍、Fe-Cr-N等模型合金和工业钢进行了辐照。用正电子湮没寿命测量、透射电子显微镜和电阻率测量对损伤结构进行了研究。在不形成金属碳化物的合金中，合金元素引起的点缺陷迁移率的变化会影响周期。在金属碳化物成形合金中，碳化物起着确定周期的重要作用。

In order to study the factors which determine the incubation period of void swelling in austenitic stainless steels, Ni, model alloys such as Fe-Cr-N and commercial steels were irradiated with electrons and neutrons. Damaged structures were investigated by positron annihilation lifetime measurement, transmission electron microscopy and electrical resistivity measurement. In alloys of no formation of metal carbides, the mobility change of point defects by alloying elements affects the period. In metal carbide forming alloys, the carbides play an important role for the determination of the period.
