Temperature dependences of physical properties and structure are investigated for the steels such as R6M5, 30KhGSA, 25Kh2G2FL, Kh18N10T, Kh12, 20Kh23N18, 80Kh20NS, 18Kh2N4MA, VNL, and ZhS26, ZhS6U nickel alloys. It is indicated that the thermal-and-time treatment during preparation of melt to crystallization increases a degree of dispersion of the dendritic structure, changes the morphology and the sizes of carbides and decreases the chemical and physical nonuniformities. Such treatment results in the improvement of plasticity, heat and corrosion resistance also.
