Methods for shaping 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, are described. The method involves heating the article in the form of a sheet or blank prior to and/or concurrently with the forming step. In some examples, the alloy is heated to a specified temperature in the range of 125 DEG C to 425 DEG C at a specified heating rate in the range of about 3 DEG C/s to 200 DEG C/s, such as 3 DEG C/s to 90 DEG C/s or 90 DEG C/s to 150 DEG C/s. This combination of the temperature and the heating rate may form an advantageous combination of article properties.

    描述用于使硬化的可热处理、可时效硬化的铝合金,例如硬化的2XXX、6XXX和7XXX铝合金或者由此类合金制成的制品,包括铝合金薄板,成形的方法。所述方法涉及在成形步骤之前和/或与成形步骤同时地对呈薄板或坯件形式的所述制品进行加热。在一些实例中,以在约3℃/s至200℃/s范围内的指定的加热速率,例如3℃/s至90℃/s或90℃/s至150℃/s,将所述合金加热到在125℃至425℃范围内的指定温度。所述温度与所述加热速率的这种组合可以形成制品特性的有利组合。
