| Abstract |
Texture and deep drawability have been investigated in Al-Mn-Mg alloy by means of orientation distribution functions(ODFs) analysis. The effect of heat treatment and cold rolling on texture varied with the process variables. Intermediate annealing before final cold rolling led to the formation of cube texture and 0°/90°earing. While, the variation of cold rolling ratio can balance the proportion of the recrystallization texture to the deformation texture so that the overall anisotropy is minimized. In the specimens cold rolled directly after hot rolling, cold rolling had more influence on earing rate than intermediate annealing. On the contrary, intermediate annealing exerted more effect on earing rate than cold rolling in the specimens intermediate annealed directly after hot rolling. |
