Study of the Mass Flow by Modeling the Flow of the Synthesized Material in the Deformation Center during SHSDeformation SHS22-Electrical Rolling of Special Purpose -Metal-Ceramic Materials and Relevant Adjustment of the Synthesis and Rolling Speeds

Abstract

The article discusses 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. Thermodynamic calculations determine the optimal composition of the charges and the parameters affecting the synthesis. A corrected empirical formula for determining the density of the charge 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 the charge density. Based on a constant distance of the front intersection of the combustion synthesis to the center of deformation (constant delay time), the change in the rolling speed for different speeds of synthesis is calculated.
