Abstract

The effects of milling time and addition of a process control agent (PCA) on the austenite stability of a nanocrystalline Fe10%Mn alloy were investigated via X-ray analysis and micrograph observation. Fe10%Mn alloy samples with nanosized crystallites were successfully fabricated by spark plasma sintering. The crystallite size was decreased by approximately 67% with an increase in milling time and the addition of the PCA. As a result, a fully austenite phase was successfully obtained owing to nanosized crystallites in the sintered samples, which enabled an increased stability of the austenite phase.
