Latent heats of phase transformations of Fe-C based metallic systems in high temperature region

Popis výsledku v původním jazyce

The paper deals with the study of latent heats of phase transformations of model Fe-C based metallic alloys and real grades of steels in high-temperature region (above 1000°C). The investigation was focused on the study of latent heats of ?<->? transformation and melting (solidification). Six model alloys were prepared and studied. Nine real grades of steels were studied as well. Latent heats of phase transformations were obtained using DTA method (differential thermal analysis). The influence of carbon, manganese and other alloyed and admixed elements on magnitude of latent heats of phase transformations was investigated. Experimental values of latent heats of ?->? phase transformation range 10-18 J/g and for transformation ?->? range 11-18 J/g. Latent heat of melting is within the range of 165-261 J/g and that of solidifying is within 162-294 J/g. Comparison of the obtained experimental data with the data presented in the literature was also carried out.
