dc.description.abstractAluminum based alloys have been widely used in the automotive, aircraft and defense applications because of good thermal and electrical conductivity, high tensile strength-to-weight ratio, high hardness, and ductility properties. Graphene, is an allotrope of carbon, attracts great attention worldwide due to its sp2-hybridized two-dimensional honeycomb structure, low weight, thermal, electrical, and mechanical properties. In the present study, high purity few- layered graphene (FLG) which was synthesized via electric arc discharge method (EAD) were reinforced to the Al-5Cu alloy matrix using various weight fraction of 0, 0.1, 0.3, and 0.5, by mechanically alloying (MA). These nano-composite powders were consolidated by cold pressing under 450 MPa and they were subjected to sintering at 570 degrees C and 580 degrees C for 3 hours under argon atmosphere. The microstructure of composites materials was studied by optical microscope and scanning electron microscopy. The FLG was observed to be dispersed homogeneously in the Al-5Cu alloy matrix. An increase in the micro hardness for Al- 5Cu alloy with 0.5 wt% FLG (123 HV) by 45 % was observed compared to pure Al-5Cu alloy (85 HV) sintered at 570 degrees C. Moreover, wear properties of these composite materials were investigated by means and analysis of variance (ANOVA).
