Present study focuses on fabricating a chromium-reinforced nickel aluminum bronze (NAB) composite using an optimized multi-pass friction stir processing (FSP) technique. The tool rotation, traverse speed, and volumetric concentration of the reinforcement were taken as input process parameters, whereas the ultimate tensile strength, yield strength, percentage elongation, microhardness, and sliding wear rate were taken as output responses. Taguchi-Grey relational analysis (GRA) was used to optimize the input process parameters, which were 1000 r.p.m., 28 mm/min and 15.7 %, respectively. The most significant parameter was traverse speed, followed by tool rotation and volumetric concentration. The fabricated composite exhibited improved mechanical and tribological performance compared to the NAB base alloy owing to grain refinement. FE-SEM, EDS, and XRD analyses were performed on the as-cast NAB, chromium powder and FS processed composite. Grain refinement was significant in the FSPed region of the composite. Microstructural examination was carried out on the fractured specimens of the NAB base material and composite. Furthermore, the worn surfaces of the specimens were examined to investigate their wear mechanisms. It was revealed that the mechanism of wear in the case of as-cast NAB was primarily adhesion, whereas abrasion was found to be the primary mechanism of material removal in the processed composite.

This study examines the impact of Friction Stir Processing (FSP) with TiO2 nanoparticle incorporation on the microstructural, mechanical, and tribological properties of AA5083 Metal Matrix Composites (MMCs). It offers a detailed analysis of the alterations in the alloy’s characteristics due to FSP. Microstructural examination was conducted using optical microscopy (OM) and scanning electron microscopy (SEM). Significant findings include the microstructural refinement where TiO2 nanoparticle addition during FSP shrank the grain size from 20 to 3 µm after one pass, which then rose to 7 µm following four passes. Mechanical properties, specifically microhardness and tensile strength, were assessed. Results indicated that after four FSP passes, the material can reach a yield strength of 192 MPa and an ultimate tensile strength (UTS) of 359 MPa, alongside a consistent microhardness of 103 HV0.1. Furthermore, it was observed that increasing FSP passes enhances energy absorption, although it remains lower than that of the base material. Analysis of fracture and wear mechanisms has led to the conclusion that with more passes, fracture mechanisms transition to a mix of ductile and brittle behaviors, and the friction coefficient decreases by up to 22.95%.
