Abstract
The effect of uniaxial tensile prestrain and subsequent annealing on the post-annealing mechanical properties (elongation, yield stress and strain-hardening exponent) of AA5182-O was investigated. Experiments were performed at four prestrain levels (5, 10, 15, and 20%) and three annealing temperatures (300, 350, and 400 °C), with holding times ranging from 5. s to 1. h. Empirical models for the yield stress of post-annealing AA5182-O were developed in terms of the applied prestrain, annealing temperature, and time for static recovery and recrystallization processes. The strain-hardening exponent was shown to have a linear correlation with the logarithm of yield stress. The above models can be used in formability analyses and forming process optimization.
