Determination of the latent heat of phase transitions in ruthenium by means of a thermionic microscope

The kinetics of phase transformation in the ruthenium specimen undergone 500 heating–cooling cycles, including transition temperatures, was studied by means of a thermionic microscope. The experimental dependence of the rate of phase interface motion on the degree of overheating was obtained. The ex...

Zusammenfassung:The kinetics of phase transformation in the ruthenium specimen undergone 500 heating–cooling cycles, including transition temperatures, was studied by means of a thermionic microscope. The experimental dependence of the rate of phase interface motion on the degree of overheating was obtained. The experimental dependence was theoretically approximated. The latent heat of phase transformations was determined.
