Abstract: The growing environmental concern to reduce fuel consumption in automotive and aerospace industries have been continuously stimulating the research and development of new magnesium (Mg) materials, as Mg with density ~ 1.74 g/cc (~ 78 % lighter than steel and ~ 36 % lighter than aluminium) is an excellent candidate for weight critical applications. However, the commercial utilization of Mg based materials is rather restricted in industrial applications due to their poor mechanical characteristics. To address some of these issues, titanium (Ti) containing Mg composite (Mg-5.6Ti) is identified as the base material in this PhD work. As Ti is insoluble in Mg, the addition of Ti to Mg metal matrix can be considered as a metallic reinforcement. With Mg-5.6Ti as base matrix, successful attempts were made to further improve its mechanical response through the combined addition of other micron or nano-sized metallic/ceramic particulates. The disintegrated melt deposition (DMD) technique followed by hot extrusion was used to synthesize the materials.
