Abstract Scope |
Weight reduction in the aerospace industry offers solutions to effectively address challenges of climate change and aircraft fuel consumption. Low-density magnesium (ρ=1.7 g/cm3) can provide a distinct advantage in weight reduction over denser light metals such as aluminum (ρ=2.7 g/cm3) or titanium (ρ=4.5 g/cm3). Developing effective techniques for joining magnesium parts to magnesium and other metals is needed to enable the widespread use of Mg in applications ranging from commercial aircraft seats to nano-satellite frames. Notably, magnesium poses liquid-phase joining challenges due to its low boiling point and high reactivity that result in welding defects and poor strength. Friction stir welding, a solid-state welding technique, has been tested on different magnesium alloys but poses difficulties in joining bulky or complex shapes and is therefore limited to joining plate components. Linear friction welding (LFW), another solid-state joining technique, is suitable for joining complex geometries and is a promising alternative for effective similar- and dissimilar-metal joining of magnesium. Our research aims at understanding the effect of LFW process parameters and alloying elements on the mechanical properties, ignition behavior, microstructure, texture, and corrosion resistance of welded Mg-to-Mg and Mg-to-Al welded sections. This work is a part of an international collaboration between the National Institute of Advanced Industrial Science and Technology, the National Research Council Canada Aerospace Research Center and McGill University, Materials Engineering. |
