Uncomplicated classical thermodynamic method of the overall description ofmetastable states is gifted. It makes attainable to calculate the explicitdependence of the Gibbs unfastened power on temperature, to calculate the warmth capacity,the thermodynamic barrier, dividing metastable and extra good states, and thethermal enlargement coefficient. Thermodynamic balance lower than mechanical loadingis thought of. The impression of the heating (cooling) cost at the measured dynamicheat potential is investigated. A part shift of the temperature oscillations of an acheated pattern is proven to be made up our minds through the comfort time of the comfort ofthe metastable nonequilibrium nation again to the metastable equilibrium one. Thisdependence permits one to calculate the comfort time. A basic description of themetastable part equilibrium is proposed. Metastable states in AB3 alloys areconsidered. purposes for the switch from the diffusional mechanism of thesupercritical nucleus development to the martensitic one because the heating fee increasesare mentioned. The Ostwald level rule is derived.
