Preparation and Microstructure of TiB₂/Al Composites

Abstract:

TiB₂/Al composites were prepared by the direct melt reaction using Al-3B master alloy and Ti powder as the reactive materials. The phase composition and the microstructure of the as-prepared composites were investigated by XRD, SEM, TEM etc.. It is showed that the reinforcement was only TiB₂, moreover, the volume fraction of the reinforcements increased with the increasing of the reactants. The TEM images showed that TiB₂ particle was in the shape of hexagonal, circle and rectangle, and its size was 0.5-2μm.
