摘要： Provided herein are high performance aluminum alloy products having desirable mechanical properties and methods of making the same. The high performance aluminum alloy products described herein contain a high content of recycled material and are prepared by casting an aluminum alloy to form a cast aluminum alloy product and processing the cast aluminum alloy product. The method of processing the cast aluminum alloy product can include two hot rolling steps.

摘要： Techniques are disclosed for casting high-strength and highly formable metal products from recycled metal scrap without the addition of substantial or any amounts of primary aluminum. Additional alloying elements, such as magnesium, can be added to metal scrap, which can be cast and processed to produce a desirable metal coil at final gauge having desirable metallurgical and mechanical properties, such as high strength and formability. Thus, inexpensive and recycled metal scrap can be efficiently repurposed for new applications, such as automotive applications and beverage can stock.

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.

摘要： A method of hot forming an aluminum alloy component may include heating the aluminum alloy component in a heating furnace to a solutionizing temperature, cooling the aluminum alloy component to a desired forming temperature, deforming the aluminum alloy component into a desired shape in a forming device while the aluminum alloy component is at the desired forming temperature, maintaining a constant temperature during the deformation of the aluminum alloy component, and quenching the aluminum alloy component to a low temperature below a solvus temperature.
