Effective duration of gas nitriding process on AISI 316L for the formation of a desired thickness of surface nitrided layer

High temperature gas nitriding performed on AISI 316L at the temperature of 1200°C. The microstructure of treated AISI 316L samples were observed to identify the formation of the microstructure of nitrided surface layer. The grain size of austenite tends to be enlarged when the nitriding time incre...
