WebApr 18, 2024 · Fig. 1(b) shows a bright-field TEM image of the quenched specimen, which also confirmed the presence of two phases, martensite and retained austenite. The martensite phase exhibits a plate-like morphology, whereas the retained austenite can be identified from the dislocation contrast close to the martensite.
