Production of structure components with selective properties by means of action media based cold forming

Abstract

Minimising a metallic component’s weight can be achieved by either using lightweight alloys or by improving the component’s profile properties. In both cases, the material formability affects the utilisability for mass production processes. Most of the high-strength materials show a material-restricted formability and are difficult to forge. The formability of a material is described by its maximum forming limit. Large plastic strains lead to mechanical damage within the material. The greater the tensile strength rate in relation to total tension rate, the faster raises the damage value. A promising approach of handling low ductile, high-strength alloys within a forming process is forming with a superimposed hydrostatic pressure by active means [1, 2, 3].
