ABSTRACT. The current work focusses on low energy laser shock peening (LSP) on graphene (0.4 wt %) – AA 2900 nano-composite fabricated through powder metallurgy (PM) technique. The added graphene serves the pinning effect and blocks the grain growth in the composite. Further, LSP has been carried out on the developed composites. As a consequence, LSP contributed the additional grain refinement effectively to the nanocomposites leading to large texture strengthening. Improvement in the hardness and tensile strength achieved with the addition of graphene and further improvement due to LSP process is achieved for the prepared nanocomposites.  

Keywords:  graphene, Laser Shock Peening (LSP), nanocomposites, ultimate tensile strength
