摘 要：Clock rolling was developed to make deformation microstructure homogenize in high-purity Ta. The substructure of deformed Ta was revealed by electron back-scatter diffraction（EBSD） technique aided with triple focused ion beam（FIB）. The results indicate that the triple FIB method can produce a mirror surface required by EBSD analysis. The clock rolling works well for the homogenization of deformed microstructure. Particularly,the local stored energy in {111} orientated grains is largely reduced by clock rolling, whereas it is enhanced in {100}orientated grains because of the occurrence of grain subdivision.
