Abstract

The paper focuses on the development of AA6061 single reinforced composites with 5 wt.% of graphite, 5 wt.% of boron carbide and a hybrid composite reinforced with 5 wt.% graphite + 5 wt.% boron carbide + 5 wt.% cerium oxide. The microstructures of manufactured single reinforced composite and hybrid composite were studied using optical microscope. The mechanical properties like hardness and tensile strength were also studied. The Vickers microhardness of graphite reinforced composites decreased from 45 VHN to 36 VHN and of boron carbide reinforced composites increased from 45 VHN to 74 VHN, while that of hybrid composites increased from 45VHN to 68VHN. The Brinell macrohardness of graphite reinforced composites decreased from 30 BHN to 25 BHN and of boron carbide reinforced composites increased from 30 BHN to 50 BHN, while that of hybrid composites increased from 30 BHN to 44 BHN. The ultimate tensile strength of graphite reinforced composites decreased from 160 MPa to 138 MPa and of boron carbide reinforced composites increased from 160 MPa to 195 MPa, while that of hybrid composite increased from 160 MPa to 175 MPa.
