In this study, a new double pin tool was utilized for the development of AA6061/316 stainless steel reinforced composite by employing friction stir processing technique first time. The microstructure, hardness, tensile, tribological, and corrosion behaviors fabricated composites were investigated comparative assessments made with results obtained from single-pin tool. showed that particle-matrix reaction did not occur in irrespective nature profile. double-pin outstandingly boosted grain refinement (7.01–5.78 μm), particle fragmentation, distribution within Al matrix due to additional pin-assisted plastic deformation, high straining, dynamic recrystallization, Zener pinning effects. improved microhardness (127–141 HV), tensile strength (162–233 MPa), resistance respect counterparts. replacement single diminished specific wear rate (0.38–0.22 mm3/Nm) composite. has favorable impact on structure, mechanical, It is thus recommended development.
