Microstructural Factors Governing Mechanical Properties in Friction Stir Welds

Article Preview

Friction stir welding (FSW) is a solid-state joining process. During FSW, microstructure drastically changes in local region of the workpiece by introduction of frictional heat and severe plastic deformation arising from rotation of the welding tool, which results in inhomogeneous microstructural distribution in the welds. To maintain high reliability of the structure produced by FSW, precise understanding of microstructural factors governing weld properties is required. In the present paper, microstructural factors governing mechanical properties, especially hardness profile and tensile properties, of friction stir welded Al and Mg alloys are reviewed.
