Simulation of the Processes of Aluminum Alloys Preforms and Semifinished Products Manufacture under Influence of Technological Heredity and Phase Transitions

Abstract:

In the present work, there are presented the results of experimental studies on the basis of regression analysis and FEM-based modeling of the processes of aluminum alloys preforms and semi-finished products manufacture including such widely known processes as cutting rolled products by shear and thixotropic stamping (stamping of metal during crystallization). It is investigated the influence of technological heredity created by variation of cant angles of end surfaces and mono- and poly-directional pulling-down by shear in cutting rolled blanks on stability of the process of subsequent longitudinal upsetting while producing preforms for bulk stamping. As a result of studying the ways of eliminating such negative consequences of technological heredity and increasing high-strength aluminum alloys technological plasticity, there is revealed the possibility of using phase transitions (from solid to liquid state and back) while manufacturing semifinished products in thixotropic conditions close to superplastic deformation.
