Bake hardening behavior and precipitation kinetic of a novel Al-Mg-Si-Cu aluminum alloy for lightweight automotive body

The natural aging (NA) phenomena and its negative effect on bake hardening (BH) response, and a wide temperature/time range of pre-aging (PA) treatment on a novel Al-Mg-Si-Cu automotive aluminum alloy were investigated systematically by micro-hardness measurement, tensile test, transmission electron...
