Structural and properties development of expanded austenite layers on AISI 316L after low temperature thermochemical treatments

Low temperature Thermochemical treatments in fluidized bed furnace involving nitriding, carburizing, and hybrid treating,sequential carburizing-nitriding, have been conducted in the present work with the aim to improve surface properties of AISI 316L. The resulting layer is expanded austenite whic...
