Study on Asymmetric Rolling Process Applied to Aluminum Alloy Sheets

Asymmetric rolling (ASR) is a method to manufacture sheet metals with the aim of improving material performance. The objective present work investigate effect asymmetric on an aluminum alloy used in automotive industry. To this end, three parameters process were studied, namely asymmetry factor (1, symmetric (SR) and 1.36, (AR)), thickness reduction per pass (10%, 15%, 30%), routes (asymmetric continuous (ARC) reverse (ARR)). After rolling, was tested by uniaxial tensile tests measure its strength formability. results show similarity between all conditions, considerable increase drastic decrease In addition, prediction forming limit diagram using FLD code based Marciniak–Kuczynski analysis evolution rolling. capable capture variation formability during process, showing that it reliable numerical tool. A reasonable combination high acceptable achieved adequate heat treatment applied after
