Model alloys based on Fe-C-Ni and Fe-C-Cr with graded carbon, chromium and nickel content were studied. Two devices with various arrangements and principle of measurement were used and solidus, peritectic transformation and liquidus temperatures were precisely determined for prepared model alloys. DTA method with simultaneous thermal analyser Setaram SETSYS 18TM and dilatometry with NETZSCH DIL 402 Expedis Supreme (NanoEye) dilatometer were performed. Phase transition temperatures were studied during crossing from solid to liquid phase. Differences between experimental and theoretical temperatures in order of dozens of degrees of centigrade were observed, especially for solidus and peritectic transformation temperatures.Keywords: DTA, dilatometry, Fe-C-Ni and Fe-C-Cr based alloys, solid and liquid phase, phase transition temperatures
