| Abstract |
In order to achieve good deep drawability it is imperative to obtain well developed {111}//ND texture which gives rise to the higher plastic strain ratios. However, it has been found that no {111} texture developed after a normal rolling process and subseguent annealing processe. Therefore an unconventional rolling process which causes shear deformation has been introduced for 99.99 pct aluminum and Al-1.2Mn-0.4Mg alloy. The effect of initial texture and microstructure on the shear texture has been studied. It is found that the rolling texture using asymmetric rolls could be characterized by α fibre and γ fibre. This experimental results were able to be explained by the Taylor-Bishop-Hill theory. The evolution of recrystallization texture from the specimen having the shear texture components was well predicted using the maximum energy release model suggested by Lee. |
