摘要

Friction stir processing (FSP) improves the mechanical properties of metals by refining grains to submicron scale. It also introduces significant basal texture in ultrafine grained magnesium alloy by tilting the basal poles by various degrees with respect to the depth in the nugget. This texture results in much higher tensile stress and ductility, but lower uniform strain in the transverse direction, than in the processing direction. This paper discusses the effect of FSP-induced texture on anisotropy in mechanical behavior.
