  • Patent number: 10391535
    Abstract: A process for making a shaped-part from a heat-treatable aluminum alloy blank comprises providing the blank in a hardened temper state, for instance the T6 or another suitable temper state. The as-provided blank is subjected to selective heating, such that a first portion of the blank is heated to a predetermined first temperature for a predetermined first length of time and a second portion of the blank is heated to a predetermined second temperature for a predetermined second length of time. The heated blank is then formed into the desired shape of the shaped-part, and is cooled to ambient temperature. The selective heating substantially increases ductility to facilitate forming of the blank into the desired shape of the shaped part, and provides desired mechanical properties within first and second portions of the shaped part corresponding to the first and second portions of the blank.
