The effect of carbon content on the c/a ratio of as-quenched martensite in Fe-C alloys

The calculated martensite peaks (002) and (200) explains the observed left-tail XRD pattern. (a) The c/a ratio of martensite in as-quenched steels as a function of carbon content, (b) The lattice parameter of martensite in as-quenched steels.179
