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......

NON-EQUILIBRIUM SOLUTE SEGREGATION TO AUSTENITIC GRAIN BOUNDARY IN FERRUM-NICKLE ALLOY D.Y.Yu1,P.Wu1,X.L.He1 (1.Department of Material Physics, University of Science & Technology Beijing, Beijing... measured by a special image analysis system. The experimental resultsof PTA show that the grain boundary segregation of boron during cooling process is adynamic process and the development of the non......
Trans. Nonferrous Met. Soc. China 28(2018) 1329-1333 Significant influence of sharp grain boundary corner on tensile elongation of copper bars with columnar grains and its mechanism Zhang-zhi SHI1... near sharp grain boundary corner promotes crack initiation and propagation, which eventually leads to the significant drop of elongation. Key words: copper; fracture; grain boundary corner; elongation......
Cavitation and grain boundary sliding during creep of Mg-Y-Nd-Zn-Mn alloy V. JAN?K1, F. HNILICA1, P. ZUNA1, V. O?EN??EK2, I. STUL?KOV?3 1. Department of Materials Engineering, Faculty... set of creep tests was interrupted after the onset of ternary creep. Fraction of cavitated dendritic boundaries was evaluated using optical microscopy. Measurement of grain boundary sliding......
