摘要：

The present paper includes the mechanical behavior of Al6061 alloy, Al6061-10TiB(2) composite and Al6061-10TiB(2)-1Gr and Al6061-10TiB(2)-2Gr hybrid composite prepared using a powder-metallurgy method. The samples were characterized by the Scanning Electron Microscope, Energy Dispersive Spectrum, X-ray Diffraction, Particle Size and Transmission Electron Microscope. Normally for Gr reinforced hybrid composite, the hardness and tensile strength decreased with increased Gr content. However, in this present study, the addition of TiB2 with nano-Gr particle improved the hardness and tensile strength up to some extent. The tensile fractured specimens were also analyzed using SEM. An acoustic emission (AE) technique was employed in all the tensile test specimens to monitor the acoustic energy released during the deformation process and for the early crack detection.
