Methods suitable for forming complex parts from work-hardened sheet materials of limited formability are described. The formability of the workhardened sheet is enhanced by forming at elevated temperature. The forming temperature is preferably selected to minimally undo the effects of work hardening so that the formed part is of higher strength than a like part formed from an annealed sheet. The method is applicable to age-hardening and non-age- hardening aluminum and magnesium alloys.
