Abstract
The present study investigated the influence of adding FeTi as supplementary reinforcement to B4C in an aluminum–silicon
(Al-12Si) matrix for automobile applications. The FeTi alloy was introduced at 3, 6, and 9 wt.% alongside 5 wt.% B4C
particles. The effects of such addition on the morphology, physical, and mechanical properties were examined. The X ray diffraction pattern identified the presence of B4C and FeTi reinforcing phases alongside Al3Fe and Ti5Si3 phases. The
examined morphology revealed that the particles were well dispersed in the matrix, with consequent effects on their properties.
Porosity was reported to reduce linearly with rise in FeTi dosage, consequently resulting in a linear increase in density and
relatively high overall density. Inclusive of the hardness, the yield and ultimate strength were enhanced progressively upon a
progressive rise in FeTi dosage, with a contrary reduction in ductility. The result revealed that the inclusion of FeTi reinforcing
fillers in the matrix is capable of ensuing appreciable improvement in the mechanical properties of the composite.
