The tensile properties and microstructures of Al alloys reinforced with AIN particles formed by in-situ reaction under a nitrogen atmosphere were analyzed. It was found that AIN particle layers formed on the surface of the A1 particles in the powder bed, which replaced the Mg3N2 coated layers through the reaction, Mg~N2+ 2A1 --~ 2AIN+3Mg. The tensile strength and 0.2% offset yield strength in the control alloys were significantly greater than those in commercial alloys. This increase was due to the fine A1N particles formed by the above in-situ reactions of the Mg,N~ formation and its decomposition into A1N.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
