Objective: To analyze the influence of various factors on the structure during the crystallization, thermal and chemical-heat treatment of steels and cast irons. Methods: Mathematical, physical and structural methods of research technologies castings. It developed methods include: research methodology transformations during continuous cooling of steel in the bulk graphite; technique to study the process of modifying vnutriformennogo; technique to study the influence of chemical and heat treatment of steel and cast iron on the formation of surface diffusion layers; technique to study the melting and crystallization processes alloys; technique to study the impact of computer-aided design of foundry equipment for casting quality; research methodology influence of various factors on the quality of the clutch bimetallic castings; technique to study the influence of isothermal annealing and isothermal hardening structural transformations and mechanical properties of tool steels. Theoretical and practical results: The regularities of structural and phase changes during crystallization, thermal and chemical-heat treatment of steels and cast irons. Proposed and investigated for effective technological options vnutriformennoy melt processing. The mathematical and graphical dependencies characterizing the effect of saturating the formation of mixtures of surface layers in a multicomponent chemical and thermal treatment of carbon steels. The dependence between the structure of the surface layer and the nature of the formation of cracks in the surface layers after chemical-thermal hardening heat treatment of steels. The possibility of obtaining bimetallic castings fusion without pretreatment of the workpiece surface, the optimal ratio of wall thickness at which it turns out quality bimetallic clutch. Novelty: Is to establish the relationships between technological factors and structural phase transitions in crystallization of alloys in the casting process, continuous cooling in the bulk graphite during heat treatment at customs construction castings, depending on their shape and size. The obtained dependences allow to develop new and improve existing processes of casting, heat treatment and thermochemical treatment of castings. Scope: Machine-building enterprises in the production of steel and cast iron.
