Abstract

An in situ Al-matrix TiB particle (10-50 μm size, ∼ 10 vol %) composite was formed by stir casting at 900°C a slurry containing liquid aluminium (2024), TiO₂, KBF₄ and Na₃AlF₆ in the weight ratio 13.5:4:1:4. The reactions among these ingredients resulted in TiB, together with small amounts of TiB₂ and TiAl₃.The composite (after T₆ heat treatment, but no secondary processing) exhibited tensile strength 270 MPa, modulus 91 GPa and ductility 8%.
