摘要：
Grain refinement and strong basal texture were produced on AZ31B Mg alloy surface concomitantly by a newly developed severe plastic deformation (SPD) process, severe plasticity burnishing (SPB). The remarkably improved corrosion resistance of AZ31 in NaCl solution after SPB was attributed mainly to dramatically reduced grain size and strongly basal-textured grain orientation. The residual stresses introduced by SPB were also found to influence the corrosion resistance to some extent Compared with other SPD processes, SPB is fast, cost-effective, does not change material bulk properties and requires little changes to the industrial production process.
