TEXTURES OF EQUAL CHANNEL ANGULAR PRESSED 1050 ALUMINUM ALLOY STRIPS

Abstract

In order to improve the deep drawability of aluminum and aluminum alloy sheets, it is desirable to increase the ND//< 111 > component in their textures. The ND//< 111 > component is known to develop in shear-deformed fcc alloy sheets. The equal-channel angular pressing (ECAP) is a process in which materials undergo approximately simple shear deformation. The deformation texture of ECAPed strips can change depending on process variables such as the texture of starting strips, the oblique angle, the number of pressing passes, and the shear direction. The deformation and deformation texture have been analyzed.
