알루미늄 5182 판재의 교차압연 및 어닐링집합조직에 관한 연구 = Cross Rolling Annealing Texture in Aluminium 5182 Sheet

다국어 초록 (Multilingual Abstract)

In order to understand the influence of the modification of deformation textures on the formation of annealing textures, the evolution of texture during the cross rolling and the subsequent annealing was investigated by employing X-ray texture measurments and microstructure observations. The β-fiber orientations were proved to be quite unstable during the cross rolling. The cross rolling led to the formation of {011}//ND fiber orientations. The cross rolled texture having uniform orientation densities along {011}//ND fiber resulted in the randomization of annealing textures. This indicated that the operation of both the oriented nucleation and the oriented growth was effectively suppressed in the cross-rolled specimen during recrystallization. Upon annealing at 500℃, the abnormal grain growth was responsible for the formation of strong {411}<011> component in the annealing texture.
