Impact Properties of Particulate Reinforced Aluminum Matrix Composites

Abstract:

TiB₂ particulate reinforcing 7449 aluminum matrix composites were fabricated by in situ method. Their microstructure and impact properties were investigated. The impact toughness decreases with the increase of the weight fraction of the particulate whereas the hardness of the composites increases. The decrease of impact toughness could be accounted for the particulate cluster and brittle clusions. The increase of the hardness is due to fine grain size and high dislocation density.
