Abstract The microstructures of Fe-Mn-Ni-Cr steels with medium carbon andthe effect of alloy elements have been investigated by means of X-ray diffractionquantitative phase analyses, metallography and hardness tests. The volume fractionof martensite in steels quenched at 1100℃ can be expressed as f_M~(1100)= 162.643 - 15.482Mn - 7.36Ni - 4.286 (Cr + Mo + V)Based on this expression, the quasi-equilibrium microstructure diagram has beenobtained.
