Abstract
Aluminum wrought alloys are usually subjected to heat treatment which includes quenching after solution treatment to improve aging responses and mechanical properties. Rapid quenching can lead to high residual stress and severe distortion which significantly affect dimension stability, functionality and particularly performance of the product. Following quenching, a mechanical stretching is usually applied to reduce as-quench residual stress and straighten the products. To model residual stress and distortion during heat treatment and mechanical stretching of aluminum wrought alloys for robust product design and durability assurance, a finite element based approach was developed by coupling a nodal-based transient heat transfer algorithm with material thermo-viscoplastic constitutive model. The integrated residual stress model has demonstrated its robustness in predicting residual stresses and optimizing heat treatment of aluminum wrought alloys.
