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......
CALCULATION OF SECOND PHASE PARTICLE-GRAIN BOUNDARY INTERACTION RANGE W. Wang1,X.L. Wang2,L.F. Hou2,Y.H. Wei2 (1.Baosteel Technology Center, Baoshan Iron & Steel Co., Ltd., Shanghai 201900, China... of Worrier, this article deals with the interaction range between the seeand-phase particle (SPP) and grain boundary (GB) as viewed from the applicability of grain boundary equation. Also, a new......
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......
-treated Ni-based cast superalloy IN792 were investigated. The results show that M5B3 boride precipitates at the grain boundary. A special orientation relationship between M5B3 phase and the matrix at one...M5B3 Boride at the Grain Boundary of a Nickel-based SuperalloyBeining Du1,2,3,Zhiwu Shi1,Jinxia Yang1,Zhaokuang Chu1,Chuanyong Cui1,Xiaofeng Sun1,Liyuan Sheng2,3,Yufeng Zheng2,31.
