Abstract
Described are processes for shaping a hardened heat treatable, age-hardenable aluminum alloys, such as hardened 2XXX, 6XXX and 7XXX aluminum alloys, or articles made from such alloys, including aluminum alloy sheets. The processes involve heating the article, which may be in a form of a sheet or a blank, before and/or concurrently with a forming step. In some examples, the alloy is heated to a specified temperature in the range of 125-425° C. at a specified heating rate within the range of about 3-200° C./s, for example, 3-90° C./s or 90-150° C./s. Such a combination of the temperature and the heating rate can result in an advantageous combination of article properties.
