On August 23, 2005, a Workshop on Shot Peening, Roller-Burnishing and Extruding took place at the Institute of Materials Science and Engineering of Clausthal University of Technology in Germany.
On this occasion, a new multifunctional shot peening machine designed and built by OSK Kiefer GmbH, Germany was introduced to more than 80 participants from Industry and University institutions from all over Germany.
This new facility which combines centrifugal, gravitational and direct pressure blast systems in a single unit supplements the shot peening laboratory at IWW consisting already of various gravitational and direct pressure blast shot peening units. The laboratory is fully equipped with a 30 kW rotating screw compressor, oil separator and refrigerant type dryer as well as with a shot sifting and sorting facility. Peening is done with a variety of shot media including cast steel, spherically conditioned cut wire, austenitic steel, and ceramic shot as well as glass beads.
As Prof. Lothar Wagner pointed out during the workshop, the Institute of Materials Science and Engineering of Clausthal University of Technology is now able to perform not only studies on thermo-mechanical treatments such as rolling, swaging and extruding to application-oriented improvements in bulk properties but can now also utilize mechanical surface treatments in order to beneficially affect surface and surface layer properties such as surface topography, amount of strengthening by cold work and last but not least residual compressive stresses.
The main goal of the Shot Peening Laboratory (SPL) at Clausthal University of Technology will be the evaluation of suitable process parameters for shot peening of a variety of metallic materials and components based on Fe, Al, Mg and Ti that will lead to optimized fatigue performance as well as increased resistances to stress corrosion cracking and corrosion fatigue. This type of research is of particular importance for the aircraft, chemical  and automotive industries.
