摘要： PROBLEM TO BE SOLVED: To provide an aluminum alloy sheet which does not generate grain streaks or living marks and is excellent in surface appearance, and a method of producing the same.
SOLUTION: In a polarization microscope image of crystals at the surface of an aluminum alloy, when the light and dark contrast in the microscope image is graded into three levels of equal intervals, the area ratio of crystals having each contrast level each falls within the range of 20-50%. In the method of producing an aluminum alloy plate by subjecting an aluminum alloy ingot to homogenization and subsequently to at least hot rough rolling and hot finish rolling, the hot rough rolling is performed employing a start temperature within the range of 400 to 610°C, a finish temperature within the range of 300 to 470°C, a rolling speed from the start of rolling of ≥50 m/min, a roll temperature of ≤150°C and a rolling amount of ≥30 mm or a single-pass reduction of ≥30%, and the hot finish rolling is performed employing a final rolling speed of ≥50 m/min, a roll temperature of ≤150°C and a total rolling reduction of ≥65%.

摘要： PROBLEM TO BE SOLVED: To produce an Al-Mg-Si based alloy sheet whose formability for pressing (especially formability for deep drawing, formability for bulging, and workability for bending) are more excellent than those of an existing Al-Mg-Si based alloy sheet specified under JIS6000 series. SOLUTION: An improved formability for pressing matched for press-forming is given by controlling, in accordance with a type of press-forming, at least the orientation density of a Cube orientation for an integrated structure of an Al-Mg-Si based alloy sheet. For example, an Al-Mg-Si based alloy sheet with an improved formability for deep drawing is provided when the ratio of an orientation density of S-orientation to that of a Cube orientation (S/Cube) is given as 1 or greater, and the ratio of an orientation density of Goss- orientation to that of a Cube orientation (Goss/Cube) is given as 0.3 or smaller, and crystal grain sizes are given as 80 μm or smaller.
