A Critical Review on Advanced Reinforcements and Base Materials on Hybrid Metal Matrix Composites

Limited availability of natural or monolithic materials all over the globe faced huge challenges for superior quality material. In this context, the hybrid composite exhibits tremendous metallurgical, physical, mechanical, and tribological properties and also in the favor of economical and eco-friendly conditions which are declared as the boon for various manufacturing and constructional sectors. This paper deals with an innovative and latest classification of hybrid composites, widely used processing routes, the examination of different material properties, modes of the testing method, and modern optimization techniques. In the present article, a novel comparative analysis for the fabrication of HYBRID MMCs through which various advanced organic and inorganic reinforcements and base materials with associated fabrication challenges and remedial outcomes are thoroughly discussed. Based on the rigorous literature review, stir-squeeze casting followed by powder metallurgy and infiltration technique is highly recommended for the better enhancement of surface morphology, density, porosity, mechanical properties (i.e. Rockwell hardness, Brinell hardness, Vickers hardness, tensile strength, and ultimate strength) and tribological properties (i.e. wear loss and coefficient of friction) of hybrid metal matrix composites.
