| Summary: | The highlights of major Canadian research projects of last two decades that aimed at advancing applications of magnesium and its alloys, being at the heart of lightweighting and ecological sustainability, are outlined. The research at universities, government laboratories, and other dedicated institutions, funded primarily through federal programs, was accompanied by strong activities of the industrial sector involved in designing and building the machinery for magnesium processing and production of components from magnesium alloys. The overall research directions matched the global trends of overcoming the key challenges that prevent magnesium alloys to play the major role in large-scale applications. Among industrially oriented projects the processing technologies in liquid, semisolid and solid states such as casting, twin roll casting, injection molding, rolling, extrusion, forging, and joining techniques were frequently pursued. Although the fundamental research aimed at understanding of a variety of magnesium behaviors and structural peculiarities up to nano and atomic levels, its essence spread around the inherently poor formability and high reactivity at room and elevated temperatures, including the ignition/flammability concerns. In recent years, a shift in research interests was observed and novel directions emerged such as magnesium air batteries, biodegradable alloys, additive manufacturing, and magnesium-rich high entropy alloys. The volume of data gathered in this report may constitute a base for specifically oriented assessments, analyses, and drawing conclusions.
