Fig. 6. Microstructures obtained in dilatometry samples observed by optical microscopy: a steel CR1, 0.06 Ks, F + P, HV 232; b steel CR2, 5 Ks, B + M, HV 555; c steel CR5, 10 Ks, M, HV 609; d steel MN4, 1 Ks, F + B, HV 327; e steel MN6, 1 Ks, B + M, HV 354. F = ferrite, P = pearlite, B = bainite, M = martensite.
