Voronko T. The thermodinamic properties of metal cerium within the critical region of gamma-alpha transition

Object of investigation is the critical phenomena and phase transitions in the thermodynamic systems. Research purpose is the obtaining and analysis of metal cerium thermodynamic properties in the critical region of gamma-alpha transition. The method of investigation is the thermodynamic method of critical state of the one-component equilibrium systems investigation. One-component heterogeneous system, its stability and the thermodynamic properties are investigated. The relation between stability characteristics and phase diagram ones is established. The obtained results are used for investigation of the metal cerium.The asymptotic behavior of metal cerium is analyzed. The conditions, for which the critical exponents' relations of simple one-component system are fulfilled as equalities, are obtained. The passage of phase equilibrium curve into the lowered stability curve is investigated. The critical exponents of Ce under different conditions of approaching the critical point have been calculated. The system critical properties are investigated on the basis thermic equation of state. The basic stability characteristics and the critical exponents are obtained for critical rigion of cerium. This being the case the basic results are gotten in the generalized form for the homogeneous onecomponent system, it allowset us to use them for investigation of the systems like critical gamma -alpha transition in the metal cerium. The investigation results can be used for the subsequent study and interpretation of the critical state nature .
