Expanded Austenite

Surface modification on 2205 duplex stainless steel (DSS) was performed by low temperature thermochemical hybrid (nitrocarburizing) heat treatment at temperature of 450° C and at holding time of 30 hours. During the process, carbon and nitrogen elements were simultaneously introduced onto the surface of DSS with composition of 5%CH4 + 25% NH3 + 70% N2. Microstructural observations reveal the formation of thick diffusional hybrid layer on the surface of 2205 DSS with very high hardness at cross sectional area. Both carbon and nitrogen diffusions formed expanded austenite (γN/C) and expanded ferrite (αC), however precipitation of nitride (Cr2N) which also occurred at the layer may deteriorate the corrosion resistance of 2205 DSS. Further investigation is required based on the parameters used in the process to produced precipitation free hybrid layer.
