Analysis of radial-shear rolling process parameters of aluminum alloys based on FEM modeling

Abstract

This article presents the features of temperature change at different deformation-velocity parameters of radial-shear rolling process. Based on modeling the maps of temperature and strain rates distribution and zone of intensive heating are obtained. It is shown that with the elongation ratio μ≥1.5, the deformation heating increases more intensively at lower heating temperatures of the workpiece. The rods are obtained from 1050A alloy (Al99.5 %) with mechanical properties (UTS ~ 111 MPa, YS ~ 109 MPa, δ ~ 15%), reflecting the partially recrystallized structure.
