WE Seminar: Joel Andersson, Fundamental Aspects of Strain Age Cracking in Precipitation Hardening Ni-based Superalloys

Abstract

New insight is presented on the fundamental aspects of strain age cracking in precipitation hardening Ni-based superalloys. Gleeble thermal mechanical simulation testing have been carried out on several superalloys and also tested at the advanced photon source outside Chicago using thermal mechanical loading coupled with in-situ small and wide angle X-ray scattering experiments to fundamentally investigate the role of hardening precipitates on the ductility response during post weld heat treatment. A brief overview of University West will also be presented.

Bio

Joel Andersson is associate professor in high temperature materials at the Department of Engineering Science, and Head of the Division of Welding Technology at University West. His research interest include welding and weldability testing of high temperature materials, specifically Ni-based superalloys, as well as fundamental understanding of welding and direct metal deposition processes and its influence on the material. Before joining University West as the Head of the Division of Welding Technology in beginning of 2016 he has been responsible for research and development of high temperature materials at GKN Aerospace Engine Systems in Sweden for about five years meanwhile being part time affiliated with Chalmers University of Technology and University West.
