Abstract

Ni47Ti44Nb9strips were successfully processed by electroplastic rolling at relatively low temperature compared to the traditional hot rolling. The result shows the deformability of Ni47Ti44Nb9is 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 Ni47Ti44Nb9after 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 Ni47Ti44Nb9owing to the short heat treatment time and low heat treatment temperature.
