Title: Qiuping Yi and Friction Stir Processing of Aluminum Alloys.
Introduction
Qiuping Yi is an inventor associated with Jimei University in Xiamen, China. Her patent work addresses friction stir processing, a solid-state technique for modifying metal materials.
Latest Patents
Yi is credited with 1 patent: “Method for Friction Stir Processing for the End Surface of Age-Hardening Aluminum Alloy Plates.” The method joins a solution-treated, age-hardening aluminum alloy plate to a dissimilar plate, then uses a rotating stirring pin to process the alloy’s end surface. It specifies maintaining a 0.01–5 mm distance between the pin’s outer edge and the alloy’s end surface. Processing takes place underwater or under liquid-nitrogen cooling, after which the alloy plate is separated and aged.
Career Highlights
The patent describes a controlled approach to processing the end surface of age-hardening aluminum alloy plates. Its use of underwater or liquid-nitrogen cooling is a notable feature of the disclosed method.
Collaborations
Wenhui Liu and Lingji Zhang are identified as Yi’s coworkers.
Conclusion
Qiuping Yi’s patent focuses on a specialized friction stir processing method for aluminum alloy plates, combining controlled tool positioning, cooling, and subsequent aging treatment.
