| Description |
The morphology, structure, and hardness variations of garnet reinforced EN AW6082 Al-alloy
composites have been investigated. High-energy ball milling of EN AW6082 Al-alloy powder,
with and without garnet reinforcement, was performed under argon atmosphere for various
duration, i.e., up to 50 hours. The study aimed at exploring the role of alloying elements and
hard reinforcement particles on the structural evolution at different stages of mechanical mill-
ing. The composite powders were characterized in terms of the morphological variation,
microstructural evolution, and thermal stability. Conventional microindentation and nanoin-
dentation measurements were carried out on the individual powders as well as composite
particles to estimate the changes in the mechanical properties of the composites with milling
time. The results reveal that incorporation of hard garnet particles hastens the milling effect and
leads to significant improvement in hardness and modulus of unreinforced pure aluminum and
aluminum alloy. This work has demonstrated the possibility of producing composites from
industrial by-product, with properties better than those of aluminum alloys and aluminum-
based composites.
