经离子渗碳或离子渗氮的奥氏体不锈钢制得扩张奥氏体。两种处理都得到过饱和氮或碳的fcc晶体结构,被高度硬化,能提高耐磨性,同时保持原有的耐腐蚀性。本项工作中研究了用离子渗碳或离子渗氮的含N和C的AISI 316L SS钢制备的扩张奥氏体,在高温(225~504℃)和具有高能(30~500 keV),高能量(~1015cm-2),短时间(~400 ns),轻离子束(氘和氦)的辐照下的稳定性。
Expanded austenite is obtained from austenitic stainless steel by ion-carburizing or ion nitriding. Both processes get fcc crystal structure that is saturated with nitrogen or carbon and is highly hardened to improve wear resistance while maintaining the original corrosion resistance. In this work, expanded austenite prepared from AISI 316L SS steels containing N and C with ionized carburizing or ion nitriding was investigated at high temperature (225 ~ 504 ℃) and high energy (30 ~ 500 keV) Energy (~ 1015cm-2), Short Time (~ 400ns), Light Ion Beam (Deuterium and Helium).
