The effects and improvements of GNPs+CNTs on the mechanical properties and microstructure of AZ80 matrix composite

AZ80 magnesium alloy reinforced by hybrid carbonaceous phase (GNPs + CNTs) is fabricated using semi-solid casting (rheocast) followed by hot extrusion (430 °C) processes through cost efficiency. This study presents the efficiency of GNPs + CNTs reinforcement in the enhancement of mechanical properti...
