摘要
The invention provides an apparatus and a method of forming a material of low ductility including providing a first sheet made from a material of low ductility, providing an integrated forming device comprising a heat source and a forming element, and moving the forming element relative to the first sheet along a forming direction while simultaneously heating a localized portion of the first sheet along the forming direction at a substantially constant predetermined distance in front of the forming element. The predetermined distance is selected so as to yield a predetermined temperature to achieve a predetermined ductility at the localized portion of the first sheet when the forming element reaches the localized portion of the first sheet.
