Precipitation hardening type single crystal austenitic steel, and usage the same |
摘要 |
In order to provide austenitic single crystal stainless steel having preferable stress corrosion cracking resistance, strength, and irradiation induced embrittlement resistance so as to extend life of nuclear reactor core structure which is used under a high radiation dose environment, a method is disclosed, which comprises the steps of homogeneously dispersing carbides into a parent phase of the austenitic single crystal stainless steel by a two step solution heat treatment, and subsequent an ageing heat treatment after rapid cooling for precipitating fine carbides. <IMAGE> |
