In the present investigation, 6082 Al based hybrid nanocomposites reinforced with multiwalled carbon nanotubes (MWCNTs) and Al-Cu-Fe quasicrystals (QC) were synthesized by mechanical milling (MM) and cryomilling (CM). In this investigation the phase evolution/ composition, morphology and thermal stability of MM and CM hybrid nanocomposites powder were studied through XRD, TEM, SEM and DSC respectively. Further efforts were made to consolidate the Al based hybrid nanocomposites by spark plasma sintering (SPS). The SPS of these MM composite were carried out at high pressure and moderate temperature to avoid the formation of Al 4 C 3 intermetallic. The microstructural characteristics and mechanical properties of these hybrid composites were studied through electron microscopy and instrumented indentation techniques & compressive testing. The present study provides an insight into the microstructural evolutions and the interfacialstrengthening of the Al based hybrid composites reinforced with MWCNTs and QCs.
