Abstract
The space morphology of martensite in 15, 45 and T9 steels quenched from high temperatures had been observed under a scanning electron microscope using a thin-foil specimen which were deeply etched. The results show that the space appearance of packet martensite is not lath-like in shape, but sheet-like in low carbon steel, and thin plate-like in medium and high carbon steels. The stereoscopic models of two kinds of packet martensite, named sheet-like and thin plate-like martensite by authors, were proposed.
