Abstract

The effect of micro-texture on fracture location in friction stir weld of Mg alloy AZ61 was investigated during tensile test. The relationship between the microstructure and mechanical properties was discussed. Tensile properties of the weld of Mg alloy AZ61 were strongly influenced by crystallographic orientation distribution as well as by grain size and dislocation density. Friction stir welding (FSW) provides defect-free welds in materials with poor fusion-weldability as a result of a solid-state joining process.
