Title:
HIGH STRENGTH 7000 ALUMINUM ALLOY MEMBER AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2014147958
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high strength 7000 aluminum alloy member manufacturing method that can improve moldability itself even after natural aging and can greatly improve strength by subsequent artificial aging curing treatment, and to provide a high strength 7000 aluminum alloy member.SOLUTION: A high strength 7000 aluminum alloy member manufacturing method is characterized by conducting extremely partial restoration processing of 7000 system aluminum alloy extrusions, for example, under particular conditions like shown in Fig. 1, without artificial refining other than natural aging, after manufacturing the extrusions; and manufacturing the high strength 7000 aluminum alloy member by performing molding in a short time to form a member after the restoration processing and performing the refining to the member.
