Special Issue Information

Dear Colleagues,

We would like to invite you to contribute to this Special Issue of Lubricants entitled Friction Stir Welding and Processing of Alloys. Friction stir welding (FSW) and processing (FSP) has gained increasing interest and importance since their invention almost two decades ago. Currently, FSW is used for joining various alloys in the shipbuilding, aerospace, automotive, and rail industries. This advanced solid-state joining technique has the potential to overcome the common issues associated with conventional fusion welding processes such as large distortions, solidification cracking, gas and shrinkage porosities, etc. FSP is a generic adaptation of FSW, where the tool is traversed along the desired path to modify the microstructure rather than joining two pieces. The FSP can be used either to modify the surface microstructure or to incorporate the second phase particles into the matrix material.

This Special Issue aims to bring together recent scientific advancements and innovations in the field of FSW and FSP with an emphasis on manufacturing and materials processing. High-quality contributions that demonstrate substantial advancements in FSW/P, variants, and applications will be considered for publication in this issue. The desired topics of contributions include, but are not limited to:

  • Friction stir welding and its variants such as friction stir spot welding (FSSW), refill FSSW, etc.;
  • Friction stir processing and its variants such as friction stir alloying (FSA), friction stir extrusion (FSE), etc.;
  • Friction stir additive manufacturing;
  • Characterization of microstructure and mechanical properties;
  • Surface properties such as surface hardness, wear, corrosion, etc.;
  • Quality inspection;
  • Equipment and tooling;
  • Process monitoring, control, and automation;
  • Modeling and simulation;
  • Manufacturing applications.

Friction stir welding (FSW) is a process by which a joint can be made in a solid state. The complexity of the process due to metallurgical phenomena necessitates the use of models with the ability to accurately correlate the process parameters with the joint properties. In the present study, a multilayer perceptron (MLP) artificial neural network (ANN) was used to model and predict the ultimate tensile strength (UTS) of the joint between the AA2024 and AA7075 aluminum alloys. Three pin geometries, pyramidal, conical, and cylindrical, were used for welding. The rotation speed varied between 800 and 1200 rpm and the welding speed varied between 10 and 50 mm/min. The obtained ANN model was used in a simulated annealing algorithm (SA algorithm) to optimize the process to attain the maximum UTS. The SA algorithm yielded the cylindrical pin and rotational speed of 1110 rpm to achieve the maximum UTS (395 MPa), which agreed well with the experiment. Tensile testing and scanning electron microscopy (SEM) were used to assess the joint strength and the microstructure of the joints, respectively. Various defects were detected in the joints, such as a root kissing bond and unconsolidated banding structures, whose formations were dependent on the tool geometry and the rotation speed.
