The creation of new, cutting-edge materials is a need of the modern era. Owing to their light weight and favorable strength-to-weight ratio, researchers in this field are creating new alloys, composites, and nanocomposites. Researchers are interested in fabricating nanocomposite materials with improved characteristics. The synthesis of an alumina-reinforced nanocomposite is the main focus of the current effort. The work identifies how fabrication of a nanocomposite's mechanical and tribological characteristics is affected by nano-reinforcement. Adding 3 wt.% alumina nanoparticles to a material improves its compressive and tensile strengths by 209.99 MPa and 203.77 MPa, respectively. However, the A3 sample composition has an improved impact strength of 78.7 Joule/cm2 and a hardness of 56.66 HV. The EBSD examination of the same sample provides quantitative information on the fraction of low-angle grain-boundaries (LAGBs) and high-angle grain-boundaries (HAGBs). The fact that the percentage of LAGBs has somewhat decreased and the percentage of HAGBs has noticeably increased definitely supports the recrystallization process in this sample composition. The apparent as well as equivalent energy fracture toughness of the A3 sample composition were both very high. They were measured in the range of 248.67 MPa√m and 309.79 MPa√m. Three body wear behavior test confirms minimum wear rate of A3 sample composition 1.6 × 10−5 and 2.2 × 10−5 for 1 kg and 2 kg load.
