Project title: Mechanical behaviour of particulate reinforced Al-TiB2 composites

This research focuses on the mechanical properties of SiC and Al2O3 particulates reinforced metal matrix composites (MMC s) fabricated by powder metallurgy (PM) and hot isostatic pressing (HIP) processes. MMCs have several advantages that are very important for their use as structural materials, i.e., high strength, light weight, high stiffness and high surface durability. However, because of its porosity PM-fabricated MMCs exhibit poorer mechanical properties. Hot isostatically pressed parts are fully densed and essentially have no porosity; as a result they exhibit improved mechanical properties. Static tensile and dynamic fatigue tests will be used to determine the mechanical and fatigue properties of TiB2 particulates reinforced MMCs.
