NANOSIZE EFFECT IN GRAIN BOUNDARY MIGRATION OF COPPER D.G.Li1,N.G.Zhou2,X.Q.Wei2,L.Zhou2 (1.Central Iron and Steel Research Institute, Beijing 100083, China;2.School of Materials Science... and leads to annihilation of the grain boundaries. The critical size is found to be 16 atomic radii. A "through intermediate grain mechanism" is identified for the nano-grain boundary motion observed......
evolutions of texture and grain boundary plane distributions in a ferritic stainless steelFANG Xiao-ying(方晓英)1, WANG Wei-guo(王卫国)1, GUO Hong(郭红)1, QIN Cong-xiang(秦聪祥)1, ZHOU Bang-xin(周邦新)2(1... energy reduction of the system is mainly caused by the grain boundary plane re-orientation in addition to minor grain growth because the distributions of grain boundary planes are moderately preferred......
mobility only serves as an assumed parameter. Many efforts have been made to measure interface mobility. In 1975, HILLERT [3] estimated the interface mobility from experiments of grain growth... [J].
