Residual Stress Reduction of Large 7050 Aluminum Forgings

7050 aluminum is a heat-treatable high-strength alloy with good fracture toughness. It is extensively used in the aerospace industry as structural components. Like many other metallic materials, heat treated 7050 alloys may contain high residual stresses, which frequently manifest themselves in distortion during subsequent operations, especially during the rough and finish machining stages. In this study, various techniques in reducing residual stresses will be reviewed, and their applications to large 7050 aluminum die forgings will be examined.
