Method of locally heating a part to reduce strength and increase ductility for subsequent manufacturing operation |
摘要 |
A method of performing manufacturing operations on a workpiece made of a high strength alloy is disclosed in which a local area of a workpiece is heated to micro-structurally soften the local area. The local area of the workpiece becomes softened and more ductile. A manufacturing operation involving deformation of the heat softened area is performed with the metal in the heat softened region being more ductile and having less strength than the surrounding portions thereof. Manufacturing operations may include riveting, clinching, hydro-forming, and magnetic pulse joining.
