Latest Patents

The provided information lists 1 patent for Liu: “Method for Friction Stir Processing for the End Surface of Age-Hardening Aluminum Alloy Plates.” The method butt-joins and clamps a solid-solution-state age-hardening aluminum alloy plate with a dissimilar plate to form a combined plate. Weld-start and lead-out plates are placed at opposite sides, and a stirring pin is positioned so its outer edge remains 0.01–5 mm from the alloy plate’s end surface. The pin is rotated into the weld-start plate, and the alloy plate is processed underwater or under liquid-nitrogen cooling. After processing, the alloy plate is separated and subjected to aging treatment.

Career Highlights

Liu’s listed invention concerns a manufacturing process designed to control friction stir processing conditions for age-hardening aluminum alloys. The described approach combines cooling, controlled pin placement, and a subsequent aging treatment.
