Pure magnesium powders are used in a variety of applications including infrared countermeasure flares, flameless-ration heaters, welding electrodes, pyrotechnics, and steel desulfurization. Powder metallurgy offers potential processing routes to tailor compositions and unique microstructures to achieve high mechanical properties in magnesium alloys. Secondary phase reinforcements including nanoparticle additions can be utilized to achieve unique combinations of strength, lightweight, wear and toughness, thus pushing the envelope of high performance lightweight applications. Furthermore, magnesium based alloys have also been widely investigated as bioresorbable implants due to their adjustable corrosion properties. This has led to emerging interests in the potential to fabricate magnesium based bespoke structures via additive manufacturing processes. This presentation will focus on the potential and challenges associated with using magnesium alloy powders for powder metallurgy and additive manufacturing processes.
