T4 - Continuum dislocation theory for severe plastic deformation of aluminium alloys

Forschungsschwerpunkte

Because of their low thermal stability, ultra fine grained materials can at present only be shaped by expensive and time-consuming processes to preserve their excellent combination of high strength and ductility. Today, amongst the various techniques that result in severe plastic deformation, there is not a single shape forming process. In this project, we study a room temperature extrusion process that will for the very first time facilitate an economically feasible fabrication of a near net shape, ultra fine grained product (simple and complex profiles).
