Defect-free joints were friction stir welded (FSW) from AZ31 Mg alloy sheets by employing optimum welding parameters for the tool geometry used. Microstructure, texture and mechanical response of the welded joints were studied to identify susceptibility of crack initiation in the different weld zones and to understand the overall fracture behavior of these welds.
A Ph.D. position is available at Texas A&M University in the Aerospace department to work on interactions between fatigue and creep (permanent deformation due to a constant mechanical stress applied) at high temperature in a superalloy. More information are in the attached file.
The candidate should have obtained a Bachelor’s or a Master's degree with a strong background in materials science, mechanical engineering or any related field. An interest for both experimental and numerical approaches is expected from the successful candidate.
Professor Gregory B. Thompson at the University of Alabama seeks post doctoral applicants for thin film and grain growth modeling in metal alloys. The qualified candidate will use modeling to explain and help direct experimental studies.
