3104铝合金冷轧变形织构的分析

Analysis of Cold Rolling Texture of 3104 Aluminium Alloy

通过对3104铝合金冷轧板的三维取向分布函数(ODF)的测算,研究和分析了该材料的织构类型与分布规律。结果表明:在冷轧过程中,所有样品的冷轧织构表现为典型的铜式(Copper-type)织构特征,其织构组分为C{112}〈111〉+B{110}〈112〉+S{123}〈634〉,随变形量的增加,织构由弱到强,最后稳定在铜织构C、黄铜织构B和S织构三个织构组分;{100}〈001〉立方织构在冷轧板中含量较弱,不足以与轧制织构相平衡。

The textures types and distribution rule of 3104 aluminium alloy during cold rolling has been investigated by means of orientation distribution functions. The results showed that the cold rolling textures of all samples during cold rolling showed typical copper-type feature and the components were C{112} <111>, B {110} < 112> and S {123} <634> .The deformation textures became stronger as the reduction increased. Finally, the cold rolling textures were composed of S-, Cu-and Bs-components.
