An Overview on Performing Low Temperature Gaseous Thermochemical Heat Treatme…

Abstract- Duplex stainless steels (DSS) which comprise dual microstructure consisting of phase balance of austenitic phase ('y phase) and ferritic phase (a phase) have been an area of interest for researchers, stainless steel producers, fabricators and end users. This paper gives a brief review on low temperature surface heat treatment processes of nitriding,Carburizing and nitrocarburiz…
