Dual-phase steel water quenched from 775°C
Same steel when quenched from 775°C. Carbides cannot be seen anymore. The microstructure is essentially martensite and ferrite. Some retained austenite can be seen as white small particles which are brighter than the background ferrite. Retained austenite measured using XRD was 3%. The step-etching technique has resulted in straw-coloured martensite, white austenite and the off-white ferrite at the background.
