High Strength and Electrical Conductivity of α-Al-CNTs + GAgNPs Nanocomposites

Abstract

AbstractThe development of new advanced material of α-Al- carbon nanotubes (CNTs and green synthesis silver nanoparticles (GAgNPs) superconductor nanocomposites was sudied. Green synthesis silver nanoparticles (GAgNPs) was used for the decoration of CNTS. The composites were by modified spark plasma sintering (SPS). The microstructure, strength and electrical conductivity of the nanocomposites were determined. The formation of sub-grain in the Al-4%CNTs + 2%GAg.NPs composite generates more dislocation density. The addition of GAgNPs to Al-CNTs significantly enhanced the ductility mode of fracture associated with the AlAg3(110) and AlAg2(100) phases and the small sub-grain formed at the surface. It can be concluded that a higher strength, electrical conductivity can be made from the developed nanocomposite.
