Abstract

Based on the FE mathematical simulation, a numerical research on patterns of metal deformation heating and temperature-field generation in a deformation zone during asymmetrical cold rolling of Al 99.5% pure aluminum, Al 5083 and Al 7075 alloys under ultra-high shear strain has been carried out. The authors have determined influence patterns of a contact-friction coefficient, rolling speed, radius of rolls, reduction ratio and strength properties of aluminum alloys on deformation heating temperature jf rolled strips. The study results can be used when developing optimal conditions of asymmetric rolling of aluminum alloys under ultra-high shear strain to achieve ultrafine grain structure and high-strength properties.

Keywords
