摘要

The Ni sheets were treated by single ball impacts in the vibration mill. The microstructural evolution and formation of the nanocrystalline grains were investigated as a function of the processing time and the ball size. The smaller balls were more effective for grain refinement. After 15-min treatment, the grain size was around 300nm for 20-mm ball and 70nm for 15-mm balls. 20-nm grain size may be attained after 30-min treatment by 20-mm ball. The difference in microstructural evolution was attributed to the impact frequency that appeared to be higher for the smaller balls at a present experimental condition. Ball collisions destroyed the initial rolling texture and could lead to the formation of the fiber texture. After 30-min treatment by 20-mm ball, microhardness increased more than five times.
