Patent number: 11255008Abstract: The present invention discloses a method for processing a highly alloyed aluminum alloy sheet with a high rolling yield, including the steps of cold rolling and hot rolling of an alloy sheet followed by heat treatment. The highly alloyed Al—Cu—Mg—Ag alloy sheet is subjected to short-time solution treatment and quenching at high temperature for multiple times by increasing the solution treatment temperature and shortening the solution treatment time. In this way, the mechanical properties of the alloy at room temperature and high temperature match with or even exceed those of a conventional alloy subjected to long-time solution treatment at high temperature. The present invention implements multiple times of short-time continuous solution treatment and quenching of a highly-alloyed coiled aluminum alloy sheet. This prevents a large amount of scraps caused by the conventional processes of segmented solution treatment and quenching of the coiled material and stretching straightening treatment.Type: GrantFiled: June 9, 2020Date of Patent: February 22, 2022Assignee: Central South UniversityInventors: Zhiyi Liu, Ye Chen, Jian Wang, Jing Cao, Song Bai
