摘要： 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.

摘要： A continuous casting and rolling line for casting, rolling, and otherwise preparing metal strip can produce distributable metal strip without requiring cold rolling or the use of a solution heat treatment line. A metal strip can be continuously cast from a continuous casting device and coiled into a metal coil, optionally after being subjected to post-casting quenching. This intermediate coil can be stored until ready for hot rolling. The as-cast metal strip can undergo reheating prior to hot rolling, either during coil storage or immediately prior to hot rolling. The heated metal strip can be cooled to a rolling temperature and hot rolled through one or more roll stands. The rolled metal strip can optionally be reheated and quenched prior to coiling for delivery. This final coiled metal strip can be of the desired gauge and have the desired physical characteristics for distribution to a manufacturing facility.
