Microstructure of Rapidly Solidified Stainless-Steel
Melt spun ribbons of series of stainless steel (FeCrNiC) alloys have been produced by rapid solidification processing to study the influence of this technique on the microstructure and distribution of γ and α phases in the ribbons. Using Mössbauer spectroscopy it has been observed that rapid quenching not only suppresses the martensite start (Ms) temperature, thus stabilizing austenite at low chromium concentrations, but that it also inhibits diffusion-assisted formation of ferrite at higher chromium concentrations.
As a whole, rapid solidification leads to an expansion of the austenite field in the Schaeffler diagram towards both lower nickel and higher chromium concentrations, and at the same time the duplex fields become narrower.
