Abstract
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 caring of the sheets. ODFs were calculated to investigate texture evolutions due to ECAP and subsequent heat treatments, The F-Value and Deltar-value were determined based on the measured pole figures to judge the formability and the caring of the samples. Experiments showed that the production of the 1050 Al alloy sheets with high formability ((r) over bar = 1.05) and low caring (Deltar = 0.05) could be possible by ECAP and the heat treatment at appropriate temperature.
