Texture evolution of the strip cast 1050 Al alloy processed by continuous confined strip shearing and its formability evaluation

Studies on texture evolutions were conducted on strip cast 1050 Al alloy sheets to assess the feasibility of equal channel angular pressing (ECAP) and subsequent heat treatments as a means for enhancing the formability while reducing the earing of the sheets. ODFs were calculated to investigate texture evolutions due to ECAP and subsequent heat treatments. The r̄-value and Δr-value were determined based on the measured pole figures to judge the formability and the earing of the samples. Experiments showed that the production of the 1050 Al alloy sheets with high formability (r̄=1.05) and low earing (Δr=0.05) could be possible by ECAP and the heat treatment at appropriate temperature.
