High-strength aluminum alloy extrusion mechanism: From the perspective of novel tool design and performance enhancement
In this study, a novel rotary extrusion tool made of H13 tool steel was designed for surface strengthening of 7075 aluminum alloy plates. The tool features an arc-shaped extrusion head with a flange connection structure. The effects of rotational speed and extrusion depth on surface morphology, microhardness, tensile p...
