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......

Inter-granular liquid phase aiding grain boundary sliding in superplastic deformation of fine-grained ZK60 Mg alloy LEE Shyong1, CHIANG Chih-te1, CHU Chun-lin1, HSU Chang-chuan2 1. Department... accommodates grain boundary sliding to reach superplasticity. On the other hand, there is no such phenomenon reported regarding Mg alloy in literatures. Scanning electron microscopic (SEM) fractography......
EFFECTS OF MODIFICATION OF THE CARBIDE CHARACTERISTICS THROUGH GRAIN BOUNDARY SERRATION ON CREEP-FATIGUE LIFE IN AUSTENITIC STAINLESS STEELS S.W.Nam1,H.U.Hong2,K.J.Kim1,K.S.Min3 (1.Dept...., 449-771, Korea) Abstract:Modification of the carbide characteristics through the grain boundary serration is investigated, using an AISI 316 and 304 stainless steels. In both steels, triangular......
