Structural and phase transformations under cooling of low-carbon martensitic steels of the Cr – Mn – Ni – Mo – V – Nb system with carbon content 0.15 and 0.27% are studied. The microstructure is investigated by optical and electron microscopy, measurement of hardness, x-ray diffraction analysis, dilatometric and energy dispersive analyses. The strength and ductility parameters are determined in tensile tests. The impact toughness is determined.
