Recent advancements in materials science have unveiled promising developments in the realm of Aluminium matrix composites (AMCs), particularly with the innovative work conducted by Sandeep Kumar Sahoo from the Metallurgical and Materials Engineering department at the Indira Gandhi Institute of Technology. His research, published in ‘Discover Materials’, delves into the synthesis of Al-Si-TiB2 composites through an in-situ method, potentially revolutionizing the construction sector.
Sahoo’s study focuses on the near eutectic and hypereutectic compositions of Al-Si alloys, utilizing a stir casting route enhanced by a salt-metal reaction involving halide salts. This method not only simplifies the manufacturing process but also significantly improves the mechanical properties of the resulting composites. “The combined effect of silicon and titanium diboride (TiB2) is a game-changer, impacting both the structure-property correlation and the hardness of the materials,” Sahoo stated.
One of the most compelling aspects of this research is the marked enhancement in wear resistance, which is crucial for construction materials that face constant abrasion and stress. The study found that increasing the silicon content in the composites led to superior wear performance under constant load conditions. This improvement is vital for applications in heavy construction equipment and infrastructure, where durability is paramount.
Moreover, the incorporation of TiB2 particles not only serves as an effective grain refiner but also contributes to reducing the size of brittle primary silicon particles in hypereutectic alloys. This refinement process results in composites that are not only lightweight but also exhibit exceptional hardness and improved tribological properties. “The clear interface between the matrix and the reinforcement, achieved through our in-situ fabrication process, is key to the enhanced performance of these materials,” Sahoo elaborated.
As the construction industry increasingly seeks materials that can withstand harsh environments while maintaining low weight, the implications of Sahoo’s findings are significant. The enhanced wear resistance and mechanical properties of these Al-Si-TiB2 composites could lead to longer-lasting components in machinery and structures, ultimately reducing maintenance costs and downtime.
This research not only highlights the potential for improved material performance but also opens avenues for further exploration in the field of AMCs. As industries continue to prioritize sustainability and efficiency, the development of such advanced materials could play a crucial role in future construction projects.
