Latest Patents

Zhang is named on 1 patent: “Method for Friction Stir Processing for the End Surface of Age-Hardening Aluminum Alloy Plates.” The invention describes butt-joining and clamping a solid-solution-state aluminum alloy plate with a dissimilar plate to form a combined plate. Weld-start and lead-out plates are placed at its two sides, and a stirring head with a pin is used while maintaining a specified distance from the alloy plate’s end surface. The process is performed underwater or under liquid-nitrogen cooling, after which the processed plate is separated and aged.
