On the Competition between Intergranular and Transgranular Failure within 7xxx Al Alloys with Tailored Microstructures

On the Competition between Intergranular and Transgranular Failure within 7xxx Al Alloys with Tailored Microstructures

7xxx aluminium series reach exceptional strength compared to other industrial aluminium alloys. However, 7xxx aluminium series usually exhibit Precipitate-Free Zones (PFZs) along grain boundaries, which favour intergranular fracture and low ductility. In this study, the competition between intergran...
