Characterization, mechanical properties, and wear behavior of functionally graded aluminum hybrid composite.

The present work demonstrates the development of SiC/TiS/AlSi12Cu hybrid functionally graded composite using centrifugal casting and examines its microstructural, mechanical, and tribological properties. A gradient distribution of reinforcement particles was observed with the outer region being particle-rich. EBSD analysis confirms microstructural refinement owing to titanium's grain refining properties and the formation of θ-AlCu intermetallic phase.
