Tic Nanoparticle Addition to Enhance the Mechanical Response of Hybrid Magnesium Alloy Muralidharan Paramsothy

A hybrid magnesium alloy nano composite containing Tic nanoparticle reinforcement was fabricated using solidification processing followed by hot extrusion. The nano composite exhibited similar grain size to the monolithic hybrid alloy, reasonable Tic nanoparticle distribution, non dominant (0 0 0 2) texture in the longitudinal direction, and 16% higher hardness than the monolithic hybrid alloy. Compared to the monolithic hybrid alloy, the nano composite simultaneously exhibited higher tensile yield strength (0.2% TYS), ultimate tensile strength (UTS), failure strain, and work of fracture (WOF) (+14%, +7%, +81%, and +92%, resp.). Compared to the monolithic hybrid alloy, the nano composite exhibited lower compressive yield strength (0.2% CYS) and higher ultimate compressive strength (UCS), failure strain, and WOF (-11%, +7%, +4%, and +15%, resp.). The advantageous effects of Tic nanoparticle addition on the enhancement of tensile and compressive properties of the hybrid magnesium alloy are investigated in this paper.
