A four-task program was conducted to provide information for the development of industrial techniques for producing improved aluminum forgings. These techniques, involving intermediate thermal-mechanical treatment (ITMT) of ingot, were evaluated on the basis of microstructure, mechanical properties, fracture and fatigue properties, and resistance to stress corrosion. The results showed that ITMT forgings have equivalent tensile properties and stress corrosion resistance and at least 20 % better fracture thoughness and fatigue properties when compared to conventional 7075-T73 forgings.
