Material Science from an Industrial Aerospace Perspective

Volvo Aero Cooperation (VAC) design and manufacture the largest aircraft engine structural parts made of the very high strength, very ductile and heat resistant aerospace material as titanium and superalloys in partnership with all major aircraft engine manufacturers as GE, P&W and Rolls Rolls-‐Royce. With these kinds of alloys, it goes without saying, that there are numerous challenges not only in the design process but also in the manufacturing processes. Due to the combination of the high strength, the good ductility and the heat resistance the superalloys are extremely difficult to machine. Since this process is important for VAC significant R&D activities have been initiated and carried at Chalmers University to understand what is fundamental in order to increase the robustness of the process and to improve the modeling. This talk will describe the research plan being undertaken and discuss opportunities for collaboration.
Göran Sjöberg is a metallurgist from Royal Institute of Technology in Stockholm having received his Ph.D. in powder metallurgy at Chalmers University of Technology in Gothenburg Sweden 1980. At ABB Metallurgy, Sweden, he was involved in developing powder metallurgy processes until joining Volvo Aero Corporation in 1988. In partnership with GE Aircraft Engines he was, as the Materials Application Engineer, responsible for the largest vacuum investment cast superalloy part in 1990 by introducing quality improvement procedures. He has carried out numerous international materials R&D project in the aerospace materials field – and in machining since 2002. In 2005 he was nominated professor at Materials and Manufacturing Department at Chalmers (Aerospace Materials) and is now supervising several Ph.D. students. Five papers from his R&D-‐ projects will be presented at the Oct. 2010 Superalloy 718 and Derivatives symposium in Pittsburgh where he also is a coordinator.
