  • Both twinning and detwinning have been reported to occur during the deformation of nanocrystalline (nc) face-centered-cubic metals. This raises the issue of how these two processes compete with each other. Here, we report that the twinning process dominates in a certain range of grain sizes, whereas, the detwinning process dominates outside of this range to annihilate all twins. These experimental observations establish a full spectrum of grain-size effects on deformation twinning and… CONTINUE READING
