Abstract Scope |
In this presentation, magnesium-based alloys reinforced with micron-sized titanium [Ti] particulates along with varying amounts of nano-sized particulates of silicon carbide [SiC] and synthesized using the technique of Disintegrated Melt Deposition [DMD] followed by hot extrusion will be highlighted. Influence of hybrid reinforcement on microstructural development of the binary composite was determined and influence of microstructure on mechanical properties established. Microstructure and properties of the hybrid composite are compared with a Mg-5.6 Ti alloy. An examination of microstructure revealed a refinement in grain size of the as-synthesized composites. This is attributed to the presence of a uniform distribution of micron-sized titanium particles along with nano-sized SiC particles coupled with resultant highly localized recrystallization. Determination of mechanical properties revealed best combination of strength and ductility for the Mg (5.6 Ti + 1.0 SiC) hybrid composite. The influence of hybrid reinforcement on microstructural development and mechanical properties will be highlighted. |
