AbstractFriction stir processing (FSP) can play an important role in grain refinement, redistribution of second phase and texture evolution. In this study, different rotation speed was employed during FSP to process Mg-Zn-Nd (ZN20) alloy with different grain size, texture and distribution of second phase. Immersion test combined with observation on corrosion morphology was carried out to evaluate the corrosion resistance of ZN20 alloy. After FSP, grain size in the alloy could be refined to 4 mu m owning to dynamic recrystallisation, the volume fraction of second phase decreased as the rotation speed increased under the influence of heat input, and strong basal texture could be formed. Finer grain size could play a positive role in improvement of the corrosion resistance by stabilising the corrosion product and acting as a barrier for corrosion cracking. Less second phase and strong basal texture cloud improve the corrosion resistance by reducing the corrosion pits.
