Abstract:

Due to their low density, magnesium Mg alloys are of interest for their potential in achieving significant lightweighting of vehicular platforms. Because many of the current Mg alloys are based on a rather small group of alloying elements, there are often limited differences between them in properties strength, corrosion resistance, etc.. In an attempt to develop new alloys that display appreciable improvements in overall performance, a series of alloys incorporating nontraditional alloying elements have been synthesized and evaluated for mechanical and electrochemical response. To facilitate insight into the influence of the respective alloying additions, a relatively simple Mg alloy AZ31B was chosen as the baseline material. Because this alloy has been extensively characterized, any improvements or reductions in performance should be more easily attributed to the alloying additions. The key metrics used, on both an individual and collective basis, to evaluate the influence of alloying additions were strength, microstructural texture, and corrosion resistance. This report provides a brief synopsis of the results obtained in the first year of this three-year effort.
