Various physical methods for the determination of phase transformation temperatures were compared using C-Mnand C-Mn-V-Nb steels. The measurement using temperature scanner, variously located thermocouples, dilatometer,diff erent thermal analysis (DTA) and anisothermal plastometric test were completed. The specimens were heated to1 323 K and 1 473 K in the case of the C-Mn-V-Nb microalloyed steel. The aim of the diff erent heat treatment were toobtain diff erent levels of precipitates’ dissolution. It was found that the better particles’ distribution and precipitationdue to the cooling lead to the enlargement of the two-phase region in the material. The good agreement ofresult gained by used methods was achieved. We found that all used methods can be used for common steels, butthe temperature scanner seems not to be precious enough for microalloyed steels.
