Structural Changes in Block-Shaped WEBAM’ed Ti6Al4V Samples after Friction Stir Processing

Friction stir welding and processing

Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a de...

Friction-Stir-Processing Effect on Fracture Toughness of Oil Pipelines in ST 37 Group Before/After Nano ZrO2-Coating

Herein, Compact-Testing (CT ) and Charpy V-Notch (CVN) testing have been done on four Friction-Stir-Processed (FSPed) samples: BM (Base-Metal), FS (FSPed-Sample), FN5 (FSP Nano-ZrO2-coated/560 rpm rotational speed) and FN9 (FSP Nano-ZrO2-coated/900 rpm), to investigate the KIC and the dominant parameters on it for St 37 steel. Experiments are also surveyed and validated by ABAQUS. Results showe...

Friction Stir Processing of Aluminum Alloys: A Literature Survey

Many aluminum alloys with specific properties, like high strength, suffers from certain limitations in terms of cost and time of production, apart from the reduction in ductility. High strength accompanied by high ductility is possible with materials having fine and homogenous grain structures. Hence there arises a necessity to develop a processing technique that would produce a material with s...
