Fatigue Enhancement Mechanism and Process Optimization of the Direct Mandrel Cold Expansion Technique on Lightweight and High-Strength Alloys

Lightweight and high-strength alloys such as Al and Ti alloys are commonly employed materials for aviation structural components. A “hole-fastener” is commonly used for their connection, and DMCE (direct mandrel cold expansion) is a reliable technique in industries to enhance the fatigue properties...
