Özet

Carbon-based nanomaterials have been attracted to the worldwide because of remarkable thermal and mechanical properties. In this study, one-dimensional multi-wall carbon nanotube (MWCNT), two-dimensional graphene nanoplatelets (GNPs) and zero-dimensional fullerene (C60) reinforced pure aluminum matrix composites were fabricated to develop mechanical properties of pure aluminum. Solution-based semi powder metallurgy technique and hot extrusion process were used for fabrication. Microstructure and mechanical properties were investigated. Hardness and tensile tests were performed to determine the mechanical performance. Results clearly show that tensile and hardness properties of pure aluminum was significantly improved even low amount (0.25 wt %) of nano carbon addition. C60 reinforced composite exhibits highest yield and tensile strength and it has best hardness value among the produced samples. (C) 2019 Published by Elsevier B.V.
