ResumoThermo-Time Treatment of multicomponent melting can be foreshadowed by the polythermal diagrams analysis of main physical and chemical properties, which are considered for this purpose as structural-sensitive properties: viscosity, surface tension, density or electrical conductivity [1]. Critical temperature (Tcr), i.e. temperature at which or around which, must run Thermo-Time Treatmenthas been experimentally marked by a sudden and seemingly contradictory deviation on polythermal diagrams of surface tension, s(T), reached out at cooling process for Ni base studied superalloy (MSRR 7045). A possible mathematical processing of it, is given by interpolation curves of the surface tensiondependence on temperature.
