Development of High Performance Magnesium Alloys: Kwang Seon Shin1; 1Seoul National University
The global market for magnesium alloys has steadily expanded in the past decade, stimulated by the strong demand for lightweight components from the automobile and electronic industries. It is important to develop new advanced magnesium alloys with enhanced formability, high strength, and improved corrosion resistance to expand the application of Mg alloys. Mg sheet formability is an important requirement for enclosure applications such as car doors, hoods, and decklids, and necessitates further improvement. In addition, the corrosion resistance of Mg alloys should be improved while maintaining high strength for automobile and bioimplant applications. This study examines various approaches for increasing the formability of Mg sheets and develops magnesium alloys with high corrosion resistance and strength using severe plastic deformation (SPD) processes such as multi-directional forging (MDF) and screw rolling (SR).

Contemporary Magnesium Die-casting Research and Technology: A Canadian Viewpoint: Jonathan Weiler1; 1Meridian Lightweight
For the last 20 years, Canada has been a world leader in magnesium die-casting research and development. The breadth of research faculty and facilities, presence of a strong industrial sector, and the participation of government funded programs and agencies have fueled significant developments. This paper provides an overview of the developments led by Canadian researchers in the field of magnesium die-casting in alloy development, property and microstructural characterization, development of ICME models, joining and corrosion technologies, and automotive product development with focus on developments funded by large-scale government funded research programs.
9:00 AM Plenary
Processing Magnesium Metal Matrix Composites Using Electromagnetic Acoustic Transduction: Michele Manuel1; 1University of Florida
A grand challenge of metal matrix nanocomposites (MMNCs) lies in processing. Magnesium (Mg) and its inherently reactive properties has virtually eliminated the ability to use conventional techniques such as powder metallurgy. A novel technology has been developed called Electromagnetic Acoustic Transduction (EMAT) to process bulk Mg-MMNCs. EMAT transforms electromagnetic energy into high intensity sonication to induce acoustic cavitation, with the goal of disrupting particle agglomeration. This plenary will explore the landscape of metal matrix nanocomposite fabrication techniques while introducing the EMAT technology and its inherent advantages. Furthermore, the physics of acoustic production and its connection to the resultant microstructure will be explained in the context of potential material property improvements.
