Abstract

This work is devoted to the decision of scientific and technical problems of the day, namely to the development of scientific and methodological bases of forming of structural and phase composition of alloys synthesized by the combined processes which consist of the metallothermic stage and SHS (self-propagating high-temperature synthesis). Alloys, synthesized metallotermy and SHS, theoretical bases of synthesis are developed relations are set between the structure of alloys, properties and descriptions of metallothermic reactions. Besides scientific bases of adjusting of properties of alloys synthesized are developed by exothermic processes with the use of metallotermic and SHS. On the basis of research the influence and terms of synthesis of different technological factors, the methods of synthesis, which allow acquiring better properties of materials are considered, compared with materials made by industrial technologies. Conformities to the law of forming of phase structure of alloys, got by the combined processes are carried out. The search of optimal structures of alloys which satisfy the preliminary set special and technological properties of materials and found out the features of the synthesized alloys is conducted. Conformities to the law of gelation are set in the poured alloys synthesized by exothermic processes depending on chemical composition, method of melting and dispersion of ingredients.
