摘要

The effects of ageing on the formability (in terms of uniaxial elongation) of aluminium alloyrnAA 6063 were studied. It was found that long natural ageing preceding artificial ageingrnhas some positive effects on both the strength and the formability of AA 6063 at testedrntemperatures. The formability decreases with increasing ageing time and increasingrnageing temperature until peak ageing is reached. At the peak ageing the formability wasrnfound to be independent of ageing temperature, even though the strength increases withrndecreasing ageing temperature. The obtained results are discussed in light of thernprecipitation reactions in the alloy.
