Aluminium matrix composites
(AMCs) play a vital role as advanced
engineering materials due to their excellent
mechanical properties like light weight,
strength, wear resistance, toughness. This
work focuses on the fabrication of
aluminium (AA6061) matrix composites
reinforced with 3%, 6% and 9% B4C particle
of 104μm using stir casting method. The
wettability of B4C particles in the matrix has
been improved by adding K2TiF6 flux in to
the molten metal. The microstructure and
mechanical properties of the fabricated
AMCs are analyzed. Uniform distribution of
B4C particle in the matrix was confirmed
using scanning electron microscope (SEM)
images. It was found that the tensile strength
and hardness of the fabricated AMCs
increases with increased B4C particle
