In this research, the phenomenon of strain-induced precipitation of M 23 (M = Cr, Fe, Mo) C6 precipitates in 347 austenite stainless steel was systematically studied. During annealing at 650 °C, the experimental results exhibited significantly earlier formation of M 23C6 precipitates in the plastically strained specimen, than in the no-strain specimen. The various microstructural characterizations showed that the accelerated formation of M23C6 precipitates occurred around deformation bands that were generated by deformation twinning. Extensive investigation suggested that the strain-induced precipitation of M23C6 is attributed to the formation of strain-induced α′ martensite during plastic deformation near deformation bands.
