Mechanical behavior of an asymmetrically rolled and annealed 1050-O sheet

Abstract

In this work, 1050-O aluminum alloy sheets are asymmetrically rolled and annealed. The asymmetric rolling process imposes intense shear deformations across the sheet thickness, leading to the development of shear texture and also grain refinement. The shear texture obtained is found to be retained after annealing. The improvements of the mechanical response and the texture evolution after heat treatment processing are inferred based on experimental shear tests and numerical simulations. It is proven that it is difficult to spread shear texture through the entire sheet thickness from a general asymmetric rolling process. Based on the fact, future research is discussed at closure.
