Clock Rolling texture and Microstructure in AA5182

AI 5182 합금 판재의 회전압연 집합조직과 미세조직

In order to understand the influence of the modification of deformation texture on the formation of annealing texture, the evolution of texture during the clock rolling and the subsequent annealing was investigated by employing X-ray texture measurements and microstructure observation. The $\beta$-fiber orientations were proved to be quite unstable during the clock rolling. The clock rolled texture having uniform orientation densities along $\{011\}//ND$ fiber resulted in the randomization of annealing texture. This indicated that the operation of both the oriented nucleation and the oriented growth was effectively suppressed in the clock-rolled specimen during recrystallization.
