| Abstract Scope |
Magnesium is actively used as a lightweight metal in the aerospace and automotive industries. It is 35% lighter than aluminium and 78% lighter than steel. Its use ensures lower fuel consumption, reduced CO2 emissions and thus a greener earth. Magnesium is also used as a lightweight metal in the consumer electronics and sports industries, replacing plastics. Here, the superior electromagnetic shielding and vibration damping characteristics of magnesium contribute to better health and well-being of the human body. This also leads to better quality of life globally. The multiple beneficial effects of Al2O3 nanoparticle addition to cast magnesium based systems (followed by extrusion) are investigated here. They are simultaneously enhanced strength and ductility of the corresponding magnesium alloys. The capability of Al2O3 nanoparticles to enhance the properties of cast magnesium alloys in a way never seen before with micron length scale reinforcements is clearly demonstrated. |
