ABSTRACT
The requirement of high performance lightweight materials in various energy saving applications has been catalytic in
the development of novel Metal Matrix Composites (MMCs) based on light metallic matrices. Magnesium is the lightest of all
metallic materials and possesses one of the highest strength-to-density ratio. Studies were made on magnesium based composites
containing ceramic reinforcements, metallic reinforcements as well as hybrid (ceramic + metallic) reinforcements. In the present
study, an attempt was made on the development of new magnesium composites containing High Entropy Alloy (HEA)
reinforcement. HEA reinforcement used in this study was in the form of ball milled particles. Mechanical properties of the
developed composite were determined in terms of microhardness and compression tests. The study showed an increasing trend in
the mechanical properties with increasing presence of HEA reinforcement. For microstructure analyses, the size and morphology
of the grains, and the size and distribution pattern of the reinforcements were investigated using optical and scanning electron
microscopy. The relation between microstructure and mechanical properties are examined to understand the behavior of newly
developed Mg-HEA composites.
