摘要:
Disclosed is an Al—Mg—Si aluminum alloy sheet that can prevent ridging marks during press forming and has good reproducibility even with stricter fabricating conditions. In an Al—Mg—Si aluminum alloy sheet of a specific composition, hot rolling is performed on the basis of a set relationship between the rolling start temperature Ts and the rolling finish temperature Tf° C., whereby the relationship of the cube orientation distribution profile in the horizontal direction of the sheet with the cube orientation alone or another crystal orientation distribution profile at various locations in the depth direction of the sheet is made more uniform, suppressing the appearance of ridging marks that develop during sheet press forming.

摘要:
An aluminum alloy sheet of specific Al—Mg—Si composition, which, owing to preliminary aging treatment under adequate conditions, has a specific metallographic structure in which there are a large number of clusters of specific size (each being an aggregate of atoms) expressed in terms of number density, which, when observed under a transmission electron microscope of 1,000,000 magnifications, appear as dark contrast in the bright field image. It is superior in paint baking hardenability and is invulnerable to room temperature aging during storage for a comparatively long period of 1 to 4 months.
