Abstract: Aluminium-titanium hydride precursors added with rice husk ash particles have been successfully foamed with improved pore structure. Initially, the powder materials were blended and compacted to produce a high density precursor. The precursor was heated to a temperature slightly above the melting point of aluminium, resulting in hydrogen gas release of hydride particles, leading to foam formation. The particles significantly influence the foam structure by increasing the viscosity of aluminium melt, modifying foam microstructure and increasing the cell wall strength, resulting in an improvement in the structure and an increase in compressive strength and energy absorbed.
