Analysis of tensile strength on friction stir welded Al 6061 composite reinforced with B₄C and Cr₂O₃ using RSM and ANN

Abstract Aluminum (Al) alloys are reinforced with carbides and oxides to enhance their properties. Al composites developed meet current automotive, shipbuilding, aviation requirements. In the study, aluminum 6061 is B 4 C Cr 2 O 3 separately fabricate Al6061 + metal matrix (Al MMC). The were fabricated by stir casting a wt % in steps of 2%, 4%, 6%. Joining MMC essential develop valuable components. welded using friction welding (FSW). FSW recognized widely used for joining due premium weld quality minimum defects. present study aims analyze effect process parameters predictive accuracy artificial neural network (ANN) response surface methodology (RSM). selected tool rotational speed, travel reinforcement %. was performed based on experimental design expert software. Through RSM analysis, it found that both independent factors (tool transverse speed) interaction jointly contribute joint higher ultimate strength 139 MPa lower tensile 48 found. As speed increase from 20 25 mm min ?1 , about 59%. average 98.26 ANN 94.86.
