| Abstract |
| Al2618 alloy composites containing 6 wt% nano B4C were prepared by liquid
metallurgy two stage stir casting process. Characterization was performed using
scanning electron microscope to validate the homogenous distribution of nano
B4C particles in the Al2618 alloy matrix. The presence of B and C elements was
confirmed by EDS analysis in the nano B4C reinforced metal composites. The
mechanical behavior of the prepared nano composites were evaluated as per the
ASTM standards, and it was noted that the tensile strength (ultimate strength and
yield strength) and compression strength increased with the addition of 6 wt%
nano B4C particles. Finally, to understand the failure mechanisms the fractography
analysis was conducted on the broken tensile specimens by using SEM images.
