An overview of the future prospects and challenges of TiC-reinforced magnesium matrix composites

Magnesium matrix composites (MMCs) reinforced with Titanium Carbide (TiC) has significant attention in the field of advanced materials due to their enhanced mechanical properties and lightweight characteristics. This Metal matrix composites (MMCs) are of great interest in industrial applications for its lighter weight with high specific strength, stiffness and heat resistance. The processing of MMCs by casting process is an effective way of manufacturing. This review paper provides a comprehensive analysis of recent advancements in the development, characterization, and applications of Mg-TiC composites. It also included synthesis methods, liquid metallurgy and powder metallurgy techniques, and the impact of TiC reinforcement on the microstructure and properties of the magnesium matrix. This review paper discusses the improvements in hardness, strength, and wears resistance achieved through TiC reinforcement, as well as the influence of reinforcement volume fraction and particle size on composite performance. Additionally, it highlights the challenges associated with the processing and fabrication of Mg-TiC composites, such as issues related to interfacial reactions and the dispersion of TiC particles. The performance of composites depends upon the right combination and composition of reinforcement material with the matrix material. The present study, based on the literature review, reinforcing material, processing route, Taguchi and GRA methods, mechanical and tribological properties of Mg based metal matrix composites containing single and multiple reinforcement. This paper presents few of the available literature review the combination of reinforcement material with magnesium matrix metal. Magnesium metal matrix composites with reinforcement(s) and filler materials are finding increased applications because of improved mechanical and tribological properties. Addition of reinforcing materials such as Al₂O3, SiC, B₄C, metallic glass, etc., is one of the ways to enhance various mechanical and tribological properties of Mg based MMCs. Waste materials may used as reinforcement such as fly ash, rice husk ash, etc. for low cost reinforcement which may results in better mechanical and wear properties. The current applications in aerospace, automotive, and structural engineering are examined, underscoring the potential benefits of Mg-TiC composites in high-performance environments. An essential goal of this review is arouse the interest of academicians, scientists/technologists and industrialists in the use of those materials for the fabrication of MMCs. This hybrid composite can replace the conventional material used in automotive applications involving tribological importance. Future directions for research are proposed, emphasizing the need for optimized processing techniques and further exploration of the mechanical behavior and long-term performance of these composites. This reviews aims to provide a detailed understanding of the state-of-the-art in Mg-TiC composites and guide future innovations in this promising material system.
