Austenite formation of carbon and alloyed steels by intense argon and nitrogen plasma pulses: Role of carbon, chromium and nitrogen

Carbon and alloyed steels were subjected to transient treatment using high intensity argon and nitrogen plasma beams. In the former case the pulses induced only the heat effects whereas in the latter—the reactive atoms generated alloying effects. Austenitic phases have been studied with the use of conversion electron Mössbauer spectroscopy. Regularities between the alloying element contents (C, N, Cr) and austenitic phases have been established and discussed.
