Abstract
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.
Claims22
