Abstract: This invention provides a method of forming a component made of an artificially and plastically formable material which can be hardened by artificial aging. The component is first shot-peen-formed in the unhardened condition and is subsequently, artificially aged. During artificial aping it is subjected to an exterior pressure load causing a creep of the impact-body-forming material to conform to a mold having the desired shape.

Abstract: A method of shaping planar parts which have an elastic and plastic range for making components which are curved two dimensionally around two axes under utilization of a high pressure peening shot beam comprises the steps of tension positioning the part to obtain through elastic deformation to obtain the desired contour; peening the surface of the part to be deformed by running a beam of shot along track lines which are essentially lines of equal strain in the parts to be made; controlling the peening shot beam energy such that more central parts receive shot at a higher energy than more peripheral parts of said part; repeating the aforementioned steps on the other side of the part; and separately peening shot treating at least some of thicker edge parts, so as to obtain plastic deformation.
