[ 1 ] - سینتیک رشد لایه آستنیت در سطح فولاد زنگ‌نزن فریتی Fe-23Cr-2/4Mo حین عملیات نیتروژن‌دهی محلولی

In this study, the kinetics of austenite layer growth on the surface of Fe-23Cr-2.4Mo ferritic stainless steel during solution nitriding and the effects of nitrogen adding on microstructure and hardness of the steel have been investigated. Steel plates of 2 mm thick were solution-nitrided at 1200˚C under nitrogen pressure of 0.25 MPa for 2, 3, 6, 9, 12 hours. Microstructure, the thicknes...
