Parameter investigation and optimization of friction stir welded AA6061/TiO2 composites through TLBO

Abstract This paper explicates the joining of AA 6061/TiO 2 composites by friction stir welding (FSW) process. FSW experiments were conducted as per three factors, three-level, central composite ivy– face-centered design method. Mathematical relationships between process parameters, namely tool geometry, speed, and rotational output responses such hardness, yield strength, ultimate tensile strength established using response surface methodology. Adequacies models assessed through analysis variance Further, elucidates application teaching–learning-based optimization (TLBO) algorithm to identify optimal values input variables obtain an joint with superior mechanical properties. The optimized experimental condition obtained from TLBO yields a UTS 174 MPa, 120 hardness 126HV. study revealed that result matched findings experiments.
