Microstructures and tensile properties of commercial pure magnesium processed by rotary swaging (RS)technique were investigated. Bulk and gradient textures in the RS processed Mg were characterised byneutron and synchrotron diffractions, respectively. Grains of the pure Mg were gradually refined withincrease in the RS passes, which largely contributed to an increase in the tensile yield strength. A dominatedbasal fibre texture was observed in the RS processed pure Mg. Accommodated twinning deformationwas also observed. Both the optical observations and texture analyses through the diameter of theswaged rod showed a gradient evolution in microstructure.
