Abstract: Ni 47Ti 44Nb 9 strips were successfully processed by electroplastic rolling at relatively low temperature compared to the traditional hot rolling. The result shows the deformability of Ni 47Ti 44Nb 9 is improved by electropulse, with the maximum thickness reduction of 24% in a single pass. X-ray spectrum and TEM analysis indicates the main structure of Ni 47Ti 44Nb 9 after electroplastic rolling is polycrystalline and Vickers hardness test shows electropulse can reduce the work hardening. In addition, electroplastic rolling can improve the surface quality of Ni 47Ti 44Nb 9 owing to the short heat treatment time and low heat treatment temperature.
