The martensite aged for about 3h at room temperatureafter either direct quenching or stepped quenching (150℃, 2 min) is the structureof M18R. The martensite just directly quenched is not so stable, both its certaindiffraction peaks and specific electric resistivity change with aging at room tempera-ture; whereas it is stable after stepped quenching (150℃, 2min), and its diffractionpeaks and specific electric resistivity change no more with aging time at room temp-erature. The above mentioned results seem to be explained by the martensite re-ordering.
