      Response Surface Methodology.

AB  - The current research designed a statistical model for the bobbin tool friction 
      stir processing (BT-FSP) of AA1050 aluminum alloy using the Response Surface 
      Method (RSM). The analysis studied the influence of tool travel speeds of 100, 
      200, and 300 mm/min and different pin geometries (triangle, square, and 
      cylindrical) at a constant tool rotation speed (RS) of 600 rpm on processing 8 mm 
      thickness AA1050. The developed mathematical model optimizes the effect of the 
      applied BT-FSP parameters on machine torque, processing zone (PZ) temperature, 
      surface roughness, hardness values, and ultimate tensile strength (UTS). The 
      experimental design is based on the Face Central Composite Design (FCCD), using 
      linear and quadratic polynomial equations to develop the mathematical models. The 
      results show that the proposed model adequately predicts the responses within the 
      processing parameters, and the pin geometry is the most influential parameter 
      during the BT-FSP of AA1050. The analysis of variance exhibit that the developed 
      mathematical models can effectively predict the values of the machine torque, PZ 
      temperature, surface roughness, hardness, and UTS with a confidence level of over 
      95% for the AA1050 BT-FSP. The optimization process shows that the optimum 
      parameters to attain the highest mechanical properties in terms of hardness and 
      tensile strength at the lowest surface roughness and machine torque are travel 
      speed (TS) of 200 mm/min using cylindrical (Cy) pin geometry at the constant RS 
      of 600 rpm. The PZ temperature of the processed specimens decreased with 
      increasing TS at different pin geometries. Meanwhile, the surface roughness of 
      the processed passes and machine torque increased with increasing the TS at 
      different pin geometries. Increasing TS from 100 to 300 mm/min increases the 
      hardness values of the processed materials using different pin geometries. The 
      highest UTS of 79 MPa for the processed specimens was attained at the TS of 200 
      mm/min and RS of 600 rpm using the Cy pin geometry.
