摘 要: 以3004鋁合金為實驗材料，研究了異步軋制對該合金的變形織構(gòu)以及相應(yīng)的制耳率的影響。實驗表明：異步軋制和同步軋制板的主要變形織構(gòu)是相同的，均為純 銅型織構(gòu){112}<111>+{213}<364>+{110}<112>，但異步軋制產(chǎn)生的變形織構(gòu)較同步軋制的強度高，且隨異步軋制速比的提高而增強。同時，異步軋制的板材中還出現(xiàn){001} <110>織 構(gòu)。另外，在相同壓下率的情況下，異步軋制板材的深沖制耳率均大于同步軋制的制耳率。

Abstract:Effects of cross shear rolling on the deformation textures and the deep drawing earing of 3004 alum-
inium alloy were studied. The experimental results showed the deformation texture is just copper type texture, {112}<111>+{213}<364>+{110}<112>, in the symmetric or cross shear rolling. However the strength of the copper type texture in the cross shear rolling is stronger and increases with increasing speed ratio of the cross shear rolling, and C component, i. e. {001} <110>, has appeared . Compared with the symmetric rolling, the cross shear rolling can result in the increasing of the deep drawing earing of the alloy sheet at the same rolling reduction.
Key words: cross shear rolling 3004 aluminium alloy texture
