Dr. Abdallah Elsayed is giving a presentation:
"Balancing Manufacturing & Performance for Energy Efficiency of Light Metal Castings for Electric Vehicles"
Emerging electric vehicles, high-performance computing components and advanced lighting systems require components with complex geometries capable of efficiently dissipating heat. These components require an alloy that exhibits high castability as well as high electrical and thermal conductivity (ETC). The Al-Si alloy system is the basis of many industrial alloys due to the ability of Si to improve castability. Unfortunately, the addition of Si is detrimental to the ETC. These contrasting properties result in two groups of Al alloys. Wrought alloys (eg. 6061) demonstrate high ETC and low castability while cast alloys (eg. 356) have good mold filling ability but low ETC. Aluminum alloys with transition metals Fe, Ni and Co show potential to form the basis of castable, high electrical/thermal conductivity aluminum alloys for heat dissipating applications. This talk discusses Al-Fe, Al-Co, Al-Ni and Al-Fe-Ni based alloys as potential castable aluminum alloys with high thermal/electrical conductivity.
This talk will also discuss some fancy laboratory techniques, which Dr. Elsayed will explain for the non-physicist audience! He used in-situ neutron diffraction to examine the solidification behaviour of aluminum and magnesium alloys. Very cool! Neutron diffraction offers unique advantages of high contrast analysis of bulk specimens, and high penetration not possible using X-ray or electron diffraction techniques. The talk will discuss some case studies of neutron diffraction for further understanding of solidification, and associated manufacturing concerns.
SPEAKER BIO: Dr. Abdallah Elsayed is currently an assistant professor with the School of Engineering at the University of Guelph. Abdallah completed his undergraduate, masters and PhD degrees in mechanical engineering at Ryerson University (Toronto, Ontario) with a research focus on light alloy (aluminum and magnesium) casting solidification and characterisation. During his studies Abdallah participated in two research exchanges at the Indian Institute of Technology-Madras (Chennai, India) investigating new grain refiners for magnesium alloys. He also collaborated with the Canadian Neutron Beam Centre in Chalk River, Ontario to examine the solidification of magnesium alloys using in-situ neutron diffraction. After completing his PhD in June 2015, Abdallah was employed at Nemak Canada Corporation located in Windsor, Ontario. Nemak is a Tier 1 automotive supplier of engine blocks, cylinder heads, transmission cases and structural components. Abdallah’s role was to conduct R&D with industry partners, universities and Nemak facilities in Canada, United States and Mexico. Abdallah joined the University of Guelph in July 2017 with a research focus on casting of aluminum and magnesium alloys for the automotive and aerospace industries. Dr. Elsayed has authored over 20 peer-reviewed publications, 5 conference proceedings and 2 book chapters. Dr. Elsayed is also Vice-Chair of the American Society of Materials (ASM) International Ontario Chapter. He is also a member of PEO, CIM and TMS.
