Abstract
Described herein are methods of processing heat treatable aluminum alloys using an accelerated aging step, along with aluminum alloy products prepared according to the methods. The methods of processing the heat treatable alloys described herein provide a more efficient method for producing aluminum alloy products having the desired strength and formability properties. For example, conventional methods of processing alloys can require 24 hours of aging. The methods described herein, however, substantially reduce the aging time, often requiring eight hours or less of aging time.
