Abstract
In the present study, AA6061-T6 reinforced with Al2O3 nanoparticulates composite functionally graded materials (FGM) is designed and manufactured via multi-step friction stir processing. The functionally graded material (FGM) was produced by two different tools of different pin geometry and by changing the weight percentage of alumina nanoparticles that are embedded in the grooves. The composite was produced by varying pin length, and a constant rotational speed of tool and traverse speeds are used. All the experiments are performed at room temperature. The microstructural features of the FGM and mechanical properties were analysed for the study of the effect of tool pin profiles. The highest average hardness in the nugget zone of 118 HV and tensile strength of 308 MPa was found in the square pin profile prepared functionally graded composite. The coefficient of friction was also least for square pin profile composite with 0.24 microns.
