An aluminium alloy sheet for use in press forming , exhibiting excellent hardening property obtained by baking at low temperature for a short period of time and a method of manufacturing the same. |
摘要 |
Disclosed is an aluminum alloy sheet having a chemical composition of an Si-containing A l -Mg-Cu alloy. The aluminum alloy sheet exhibits a streak-shaped modulated structure at a diffraction grating points of an A l -Cu-Mg system compound in the electron beam diffraction grating image. The above mentioned streak can be generated efficiently when the alloy essentially consists of 1.5 to 3.5% by weight of Mg, 0.3 to 1.0% by weight of Cu, 0.05 to 0.6% by weight of Si, and the balance of A l and inevitable impurities, and the ratio of Mg/Cu is in the range of 2 to 7. <IMAGE> |
