Armour College of Engineering’s Department of Mechanical, Materials, and Aerospace Engineering will welcome Dr. Mohsen Mohammadi, an Associate Professor and Director of the Marine Additive Manufacturing Centre of Excellence (MAMCE) at the University of New Brunswick, to present his lecture, “A Path Forward to Additive Manufacturing of Special Alloys: Processing, Characterization, and Multiscale Modeling.”
The virtual seminar will take place on Wednesday, January 27, 2021, from 3:30–4:30 p.m. Contact Elena Magnus at email@example.com for the seminar details and a link to join.
Additive manufacturing techniques have recently gained much attention in different industries including medical, aerospace, energy, and marine. This is mainly due to several advantages that these methods present including shorter lead time and fewer design complications. Of particular interest is metal additive manufacturing techniques that compared to conventional counterparts offer improved mechanical properties due to hierarchal and ultrafine microstructures resulted from high solidification rates. A brief overview of the use of metal additive manufacturing techniques in marine and defense applications (aluminum, stainless steel, bimetals) is provided. In addition, a comprehensive experimental methodology to characterize these alloys after laser and electron beam processing using advanced electron microscopy techniques is then presented. Furthermore, a multiscale simulation framework to model the performance of these alloys from solidification up to their service is presented. Finally, a path forward to use additive technologies of specialty alloys in industries with severe service conditions is presented.
Dr. Mohsen Mohammadi is an Associate Professor of Mechanical Engineering and Director of Marine Additive Manufacturing Centre of Excellence (MAMCE) at the University of New Brunswick (UNB). Dr. Mohammadi is working on developing and optimizing the performance of advanced materials made using metal additive manufacturing techniques. His current research is on enhancing the mechanical, corrosion, impact, and fatigue properties of additively manufactured alloys (aluminum, titanium, steels), metal matrix coatings, and ultra light and high strength metamaterials. Prior to starting his academic career at the UNB in 2015, he worked as a research associate and postdoctoral fellow at the University of Waterloo, NSERC visiting research fellow at CanmetMATERIALS, and PhD candidate at the University of Western Ontario. Dr. Mohammadi leads different projects on adopting metal additive manufacturing in marine, defense, and aerospace sectors.
