Résumé

 There has been a constant drive for replacing monolithic aluminum alloys by aluminum-based metal matrix composites (MMCs) in many industrial applications where high stiffness and high strength to weight ratio are required. The present paper describes a cost-effective route to produce Al-Alloy-10 wt % TiB2 metal matrix composites by in situ molten flux assisted reaction synthesis. In Situ LM25-TiB2 composite material prepared by reaction synthesis was cast into thick as well as thin section industrial components by gravity and pressure die casting route. Subsequent structure-property evaluation studies indicated sub-micron size reinforcement of in situ formed TiB2 particles with improved physical and mechanical properties as compared to conventional aluminum alloy and its composites. From industrial point of view, the Al-TiB2 composite has an advantage of easy recyclability over conventional aluminum-alloy composites. Keywords: Alloy, metal matrix, composites
