摘 要：In present paper, the effect of enhanced solution on mechanical properties and aging behavior in a commercially available 2024Al alloy were investigated using tension test and scanning electron microscopy. Differential scanning calorimeter (DSC) was used to measure the incipient melting behavior and then determine the technology parameter of enhanced solution heat treatment for high strength. The results show that an appropriately enhanced solution treatment can make final solution temperature higher than that of the conventional solution temperature and improves second phase solution without the formation of overheated microstructure. As the results, both the strength especially the yield strength and the resistance to over aging can be improved considerably without a large deterioration to tensile ductility.
