DEVELOPMENT OF NEW MAGNESIUM BASED MATERIALS FOR ENGINEERING APPLICATIONS

Abstract

Magnesium materials are more preferred especially for weight critical applications without compromising on the overall strength of the product. For realizing simultaneous improvements in the strength and ductility of magnesium materials, when compared to alloying and grain refinement, addition of nanoparticulates as reinforcements to magnesium matrix is considered as a promising technique. In the present study, effects of: (1) Ti based reinforcement in the form of nanoparticulates: (a) metallic titanium, (b) ceramics of titanium such as titanium diboride (TiB2), titanium carbide (TiC), titanium dioxide (TiO2) and titanium nitride (TiN), (2) primary synthesis techniques such as disintegrated melt deposition (liquid-phase) and powder metallurgy (solid-phase) on Mg-TiO2 nanocomposites containing TiO2 nanoparticulates, and (3) morphology of titanium dioxide (TiO2) in the form of nanofibers and nanoparticulates on the microstructural and mechanical properties of pure magnesium in the absence of microstructural factors related to the presence of precipitates and heat treatment are investigated.
