Fig. 3.. Simulated microstructures of an austenite grain with high RA content (50 % RA) subjected to stress cycling. Microstructure (a) before the stress cycling (as-quenched), (b) after completion of loading part of stress cycle-1 in the low stress regime, (c) after completion of stress cycling in the low stress regime, (d) after completion of stress cycling in the high stress regime. Martensite variants 1, 2 and 3 are shown in red, blue and green, respectively. Areas of martensite reversion are shown by ellipses (white).
