Multipass Friction Stir Processing of Laser-Powder Bed Fusion AlSi10Mg: Microstructure and Mechanical Properties
The effect of multipass friction stir processing (FSP) on the microstructure and mechanical properties of an AlSi10Mg alloy produced by laser-powder bed fusion was investigated. FSP was performed at a rotational speed of 950 rpm and traverse speed of 85 mm/min. The results indicated that FSP destroy...

| description | The effect of multipass friction stir processing (FSP) on the microstructure and mechanical properties of an AlSi10Mg alloy produced by laser-powder bed fusion was investigated. FSP was performed at a rotational speed of 950 rpm and traverse speed of 85 mm/min. The results indicated that FSP destroyed the coarse grain structure in the as-built AlSi10Mg by generating fine and equiaxed grain structures with shear texture components of <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msubsup><mi>A</mi><mn>1</mn><mo>*</mo></msubsup><mrow><mo>(</mo><mrow><mn>111</mn></mrow><mo>)</mo></mrow><mrow><mo>[</mo><mrow><mover accent="true"><mn>1</mn><mo>¯</mo></mover><mover accent="true"><mn>1</mn><mo>¯</mo></mover><mn>2</mn></mrow><mo>]</mo></mrow></mrow></semantics></math></inline-formula> and <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msubsup><mi>A</mi><mn>2</mn><mo>*</mo></msubsup><mrow><mo>(</mo><mrow><mn>111</mn></mrow><mo>)</mo></mrow><mrow><mo>[</mo><mrow><mn>11</mn><mover accent="true"><mn>2</mn><mo>¯</mo></mover></mrow><mo>]</mo></mrow></mrow></semantics></math></inline-formula>, in addition to causing fragmentation and refinement of the Si networks. FSP reduced the tensile strength slightly but significantly improved ductility. One-pass FSP exhibited superior mechanical properties compared with the two- and three-pass scenarios. The higher strength of the one-pass sample was attributed to the strengthening mechanisms induced by the Si particles, which were grown by repeated FSP. The higher ductility of the one-pass sample was explained using the kernel and grain average misorientations. Furthermore, the post-FSP microstructural evolution and fracture behavior of the samples were discussed. |
