METHOD FOR THE MANUFACTURE OF AN ALUMINIUM ALLOY PLATE PRODUCT HAVING LOW LEVELS OF RESIDUAL STRESS

摘要

The invention relates to a method of the manufacture of a thick gauge aluminium alloy plate having reduced level of residual stress, said method comprising (a) providing a solution heat-treated and quenched aluminium alloy plate having a thickness of at least 80 mm, (b) stress-relieving said plate by cold rolling the plate to achieve a reduction in the thickness direction of the plate product in a range of up to 8%.
