Magnesium is the lightest and one of the most abundant element in universe. Besides, magnesium possesses several other benefits like excellent castability, high damping capacity, good electromagnetic shielding, excellent machinability and less energy requirement in production compared to aluminum. These inherent characteristics of magnesium based materials ensures fuel economy, reduced CO2 emissions and a greener earth. Further, as magnesium based materials are almost 35% lighter than aluminum based materials, a tremendous surge in magnesium demand over next 5 years is expected.
One of the ways in which the engineering capabilities of magnesium and its alloys can further be enhanced is to use composite technology. The addition of nanoparticles, for example, leads to enhanced tensile, compressive, fatigue, creep, dynamic, tribological and corrosion properties. In addition, amorphous and hollow reinforcements can also enhance targeted mechanical/physical properties. Accordingly, the present presentation will highlight the key capabilities of magnesium based composite technology.
