    This study addresses the limited understanding of how nano-materials affect the mechanical properties and wear behavior of AMMNCs, focusing on challenges in achieving uniform nano-material distribution and optimizing processing parameters. This study explores the fabrication and tribological performance of Al7075 hybrid metal matrix nano-composites reinforced with TiC and Graphene using ultrasonic stir casting. By varying TiC content (0.5 to 2.5 wt%) and maintaining 0.25-wt% Graphene, the composites were tested under dry sliding conditions. Results indicate that the hybrid nano-composite with 1.5 wt% TiC and 0.25 wt% Graphene exhibits optimal wear resistance and frictional behavior, attributed to improved hardness and reduced surface damage. This results from harder particles intermingling with the softer alloy, which shows increased hardness with reduced delamination, cracks, and fractures of inside surfaces during wear. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.
