TEXTURE DEVELOPMENT AND DRAWABILITY OF FRICTIONALLY ROLLED AA 5052 AL ALLOY SHEET

Abstract

The microstructure, pole figure and r-value of the frictionally rolled and subsequently heat treated AA 5052 Al sheets were investigated by optical microscopy, x-ray diffractometer and tensile tester, respectively. Frictionally rolled AA 5052 Al specimens showed a fine grain size. After subsequently heat treated specimens, the ND//< 111 > texture component was increased. The r-values of the frictionally rolled and subsequently heat treated Al alloy sheets were about two times higher than those of the original Al sheets. These could be related to the formation of ND//< 111 > texture components through frictional rolling in and subsequent heat treatment of AA 5052 Al sheet.
