Residual stress investigation of quenched and artificially aged aluminum alloy 7175

Residual stresses on aluminum parts can be modified during heat treatments. During solution heat treatment, quenching, and aging, metallurgical transformations combined with thermal gradients lead to a modification of parts properties. Quench and aging treatments sensitivity of AA 7175 aluminum alloy components is addressed in this work. Samples have been subjected to various quenching and aging treatments to verify the actual effect of the...
