When implementing this method to obtain a reliable connection at the interface of two materials, special attention is paid to the uniform heating of the flat workpiece, which is achieved by the correct choice of the inductor configuration and processing modes. For this purpose, two configurations of the inductor are considered in the work: a flat ellipsoid type, which acts only on one surface of the workpiece, and a spiral inductor of the solenoid type, which covers four surfaces of the workpiece. The technological scheme provides for obtaining two-layer and three-layer products with the formation of a working layer, both from one surface of the workpiece and from its two side surfaces. As a result of simulation modeling, patterns of energy distribution based on current strength and heating time were established for two configurations of inductors. The distribution of temperature fields in the steel billet is considered. The hydrodynamic features of filling the mold with melt and crystallization of the casting have been established. The influence of technological parameters such as the temperature of pouring the melt and the temperature of heating the steel billet on obtaining a high-quality bond was studied. Experimental studies on obtaining a reliable bimetallic connection based on iron-carbon "steel-cast iron" alloys were conducted. The results of physical and mathematical modeling of the temperature fields of the workpiece are compared. Adaptation of simulation modeling relative to the physical model has been carried out. A study of the structural composition and properties of the obtained samples based on iron-carbon alloys "steel-cast iron" was carried out. It was established that the formation of transition layers in bimetallic samples is determined by the processes of diffusion Product Description popup.authors Likhatsky Richard F Shmatko Oleksandr V popup.nrat_date 2023-01-11 Close
