Abstract :ABSTRACT In this study, retained austenite contents in carburized   SAE 8620 insert ignore into journalissuearticles values(21NiCrMo2); steel were investigated. Carburizing programs were carried out in gas atmosphere at 940°C. X-ray diffraction was used to determine retained austenite contents in the case-hardened microstructures of the carburized specimens. Test results indicated that maximum retained austenite contents at the microstructures of the carburized specimens that carburized 45 minute, 3 h and 5 h carburizing times at 940°C were 35.8%, 19.4% and 15%, respectively.     Key Words : Carburizing, Retained austenite, X-ray diffraction
