Vikas Shrivastava, a renowned expert in the field of nanoalumina reinforced aluminium metal matrix composites (AMMCs), has made significant contributions to the development and characterization of these advanced materials. The use of nanoalumina as reinforcement in aluminium metal matrix composites has attracted much attention due to its unique properties, such as high strength, wear resistance, corrosion resistance, and thermal stability.
Shrivastava has extensively researched the synthesis and characterization of these composites, focusing on their mechanical properties, tribological properties, thermal properties, and electrical properties. The microstructure of the composites has been studied in detail, and various processing techniques such as sintering, powder metallurgy, casting, extrusion, mechanical alloying, spark plasma sintering, hot pressing, and cold pressing have been explored to fabricate these materials.
One of the main advantages of these composites is their excellent mechanical properties, including high hardness, tensile strength, compressive strength, fatigue strength, fracture toughness, yield strength, elongation, and ductility. The use of nanoalumina as reinforcement has also improved the wear resistance and tribological properties of the composites, making them ideal for various industrial applications.
Shrivastava has also studied the surface properties of these composites, such as their interface bonding, adhesion, and cohesion. He has shown that the addition of nanoalumina has improved the surface properties of the composites, leading to better machinability and weldability.
Overall, Shrivastava's research has provided valuable insights into the development and characterization of nanoalumina reinforced aluminium metal matrix composites, demonstrating their potential for various industrial applications. The use of these materials could lead to significant improvements in the performance and durability of various engineering components.
