Fabrication and properties of Al-TiAl3-Al2O3 composites with high content of reinforcing particles by accumulative roll-bonding and spark plasma sintering

It has been expected that mechanical properties of a composite can be enhanced effectively by increasing the content of reinforcing particles to high levels, for which a simultaneous fulfillment of high content and uniform distribution of reinforcing particles is key. In this study, we fabricated Al-TiAl3-Al2O3 composites from starting materials of Al sheets and TiO2 nanopowders by combining accumulative roll-bonding and spark plasma sintering...
