Abstract:
An optimum combination of strength and toughness is required in many
applications. A composite material can be synthesized with tailored properties by
varying the amount of reinforcement in a matrix. CoFeNi was selected as the
matrix to provide ductility and toughness to the composite. Composition of the
ternary alloy was equi-molar which lies in the FCC range in the phase diagram.
FCC was preferred as it is more ductile than BCC, HCP and intermetallic phases
due to its active slip systems. WC particulates were added as a reinforcement to
impart strength to the composite. The amount of WC added to the matrix was 1.0
and 2.0 wt.% and its effect on strength was studied. Characterization revealed an
increase in hardness of the composite with addition of WC in the matrix
