Process Combination of Combined Deep Drawing and Cold Forging

Funding: German Research Foundation (DFG)
Project: TE 508/61-1
Contact: Oliver Napierala M. Sc.

The combination of different materials represents a possibility to adjust the local mechanical properties of a component and to reduce the weight by a suitable choice of materials.

Prevention of Longitudinal Weld Streak Defects on Anodized Aluminum Profiles

Funding: AiF/Stifterverband Metalle
Project: 18756 N
Contact: Johannes Gebhard M. Sc.

Anodized profiles are widely used as visual components. A common defect is the occurrence of longitudinal weld streaks on the surface, which depend on the whole process chain from casting of the billets to anodization of the extruded profiles.

Influencing the Evolution of Damage in Cold Extrusion

Funding: German Research Foundation (DFG)
Project: CRC/TRR188 • Subproject A02
Contact: Oliver Hering M. Sc.

The properties of cold forged components are a consequence of residual stresses, strain hardening, and the resulting damage along the process chain.

Manufacture by Forming and Characterization of Actuator Profiles Based on Shape-Memory-Alloys

Funding German Research Foundation (DFG)
Project TE 508/45-2
Contact Christoph Dahnke M. Sc.

Shape memory alloy wires can be continuously embedded in aluminum or magnesium profiles by means of composite extrusion. Due to the extraordinary properties of the NiTi wires, such as the shape memory effect and superelasticity, improvements of the mechanical properties of the composite can be achieved.
