Al-Mg-Si 系合金板材において，再結晶集合組織の形成に及ぼす冷間圧延率の影響について調査を行った。Cube（｛001｝<100>）方位密度は冷間圧延率に応じて劇的に変化し，67%を超える高冷間圧延率では急減した。一方，Cube方位の急減に伴いCubeND方位（｛001｝<520>），R方位（｛123｝<634>），P方位（｛011｝<111>）の方位密度は増加した。部分再結晶組織の観察から，このCube方位密度の減少，およびCubeND，R，P方位の発達の主要因は粒子促進核生成（PSN）機構によるものと推察され，また，再結晶組織の発達には再結晶粒と周囲のマトリックス（圧延集合組織）の方位関係が重要であること が示唆された。
The effect of cold rolling reduction on development of recrystallization textures in an Al-Mg-Si alloy was investigated. The orientation density of Cube ({001}<100>) texture after the annealing at 833 K decreased dramatically at over 67% cold rolling reduction. However, CubeND ({001}<520>), R ({123}<634>), and P ({011}<111>) textures increased with decreasing orientation density of Cube. The decrease in orientation density of Cube and the increase in orientation density of CubeND, R, and P were assumed to be mainly caused by particle stimulated nucleation (PSN). In addition, this study suggested that development of recrystallized textures was affected by orientation rotation relationships between recrystallized grains and surrounding deformed matrix.
