Abstract
Near-surface macroscopic compressive residual stresses in a deep-rolled aluminium alloy AA6110-T6 (Al–Mg–Si–Cu) were measured during cyclic loading at elevated temperatures as a function of loading cycle. Thermal residual stress relaxation was investigated and analyzed by applying the Zener–Wert–Avrami function. The effects of stress amplitude as well as temperature on residual stress relaxation during stress-controlled cyclic loading at elevated temperatures were systematically investigated and analyzed using separate assessment of mechanical and thermal residual stress relaxation.
