Study of the Mass Flow by Modeling the Flow of the Synthesized Material in the Deformation Center during SHS-Electrical Rolling of Special Purpose Metal-Ceramic Materials and Relevant Adjustment of the Synthesis and Rolling Speeds

Abstract

The study of mass flow during plastic deformation of metal-ceramic materials on the basis of Ti-B and Ti-BN system with SHS-electrical rolling is discussed in the work. Thermodynamic calculations determine the optimal composition of the cells and the parameters affecting the synthesis. A corrected empirical formula for determining the density of the case in the center of deformation, during the transition from the entry section to the exit section, is given. The so-called “negative” stretching event is analyzed and the length increase of the synthesized material is determined on the basis of different stretching regimes and changes in case density. Based on the condition of a constant distance of the intersection of the synthesis combustion front to the center of deformation (constant delay time), the change in the rolling speed at different synthesis speeds is calculated.
