We used machine learning (ML) to analyze the tensile strength of aluminum nanocomposites reinforced with m-SiC particles fabricated by ARB. The effect of ARB passes on the microstructure, phase analysis, tensile, and hardness properties was investigated. The experimental results showed the improved distribution of SiC particles with increasing ARB passes. The developed ML model, based on the Growth Optimizer Algorithm, accurately predicts the tensile properties of the composites.
We discovered and analyzed the new prediction model by using machine learning (ML) for the tensile strength of aluminum nanocomposites reinforced with m-SiC particles fabricated by accumulative roll bonding (ARB). The effect of the number of cycles and SiC content on the microstructure, phase analysis, tensile, and hardness properties have been investigated for the ARBed sheets and their composites. The experimental results showed the distribution of SiC particles improved by increasing ARB passes. The ARB approach greatly enhanced the ultimate tensile strength (UTS), yield strength (YS), and hardness. The UTS achieved was 254 MPa for 4% SiC after 9 ARB cycles. The hardness values of the ARBed AA1050, and AA1050-4 wt% SiC are 60, and 76.5, respectively, after 9 ARB cycles. The modified version of random vector functional link based on Growth Optimizer Algorithm is developed as a machine-learning model to predict the tensile properties of the produced composites. The efficiency of the developed ML model is evaluated with other methods according to the performance criteria.& COPY; 2023 The Author(s).
