This paper reports improved mechanical properties of AZ91 magnesium alloy at room temperature. Titanium particles dispersed AZ91 magnesium alloy composite is produced through accumulative diffusion bonding (ADB) process. Vickers hardness, ultimate tensile strength and 0.2% proof stress increased with increasing the amount of titanium particles. The composite with 2.0% Ti produced by the ADB process showed significantly high elongation over 30%. Improved ductility would be due to random texture development by severe plastic deformation and stress relaxation by titanium particles.
