Mechanical properties of Al7075 alloy with nano-ceramic oxide dispersion synthesized by mechanical milling and consolidated by equal channel angular pressing

► Homogeneous dispersion of nano-TiO2 in Al7075 achieved by mechanical milling (MM). ► Dense (∼3 Mg/m3) product achieved by equal channel angular pressing (ECAP). ► Significant improvement in hardness and compressive strength obtained after ECAP. ► No significant preferred orientation rather random texture retained after ECAP. ► Present approach (MM + ECAP) can develop nano-TiO2 dispersed Al-matrix composites.
