The Influence of Novel Alloying Additions on the Performance of Magnesium Alloy AZ31B
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 addition(s), 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.
