摘要： 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.

摘要： Processes for improving the strength of heat-treatable, age hardenable aluminum alloys, such as 6xxx, 2xxx and 7xxx aluminum alloys, are provided. The processes for improving the strength of heat-treatable, age-hardenable aluminum alloys involve a heat treatment step, termed "shock heat treatment," which involves heat treatment at 200 to 350 °C that is conducted at a fast heating rate (for example 10 to 220 °C/seconds) for a relatively short period of time (for example, for 60 seconds or less or for 5 to 30 seconds). In some examples, the shock heat treatment is accomplished by contact heating, such as heating an aluminum alloy article between complementary shaped heated dies of a press. Aluminum alloy articles, such as automotive panels, produced by the disclosed shock heat treatment are also provided.
