Interfacial dislocations dominated lateral growth of long-period stacking ordered phase in Mg alloysQianqian Jin1,Xiaohong Shao1,Shijian Zheng2,Yangtao Zhou1,Bo Zhang1,Xiuliang Ma1,31. Shenyang.... The LPSO/Mg interface features the unique configuration of the Shockley partial dislocations, which produces a near zero macroscopic strain because the net Burgers vectors equal zero. The 18 R/Mg interface......
Atomistic Simulation of Interaction between Grain Boundary and Dislocations in Ni3AlDongliang LIN(T.L.Lin) Da CHEN Min LU Department of Materials Science,Shanghai Jiaotong University... to simulate the interaction between the grain boundary(GB) and dislocations in Ni3Al alloys.The focus has been placed on the energy feature of theinteraction,the distortion of GB structural units......

Influence of relative positions between RF coil and crucible onsapphire crystals by edge-defined film-fed growth (EFG) techniqueWU Xiao-feng(吴小凤)1, YAO Zheng-jun(姚正军)1, PEI Guang-qing(裴广庆)2, LUO Xi... coil and crucible on the performances of sapphires produced by edge-defined film-fed growth (EFG) technique was investigated. For comparison, the crucible was located at the top (case......
Atomic-resolution studies on reactions between basal dislocations and {10■2} coherent twin boundaries in a Mg alloyHuhu Su1,Xinzhe Zhou1,Shijian Zheng2,Hengqiang Ye1,3,Zhiqing Yang11. Shenyang... Laboratory of Reliability and Intelligence of Electrical Equipment, Hebei University of Technology摘 要:Reactions between basal
line and corners of image. The linear filter extends or blurs the boundary of image. The anisotropic diffusion removes random noise effectively, but it brings about illusive edge and back diffusion... characteristic such as corner, thin line and edge. Key words: mixed noise; anisotropic diffusion; outlies; edge ......
板坯角横裂纹在轧后钢板边部的延展行为刘洋1,顾林豪1,李战军1,王文军1,吕延春1,王海宝1,姜中行1(1.北京市首钢技术研究院)摘 要:对板坯角横裂纹在轧后钢板边部的延展行为进行了实验室和工业试验研究.得出:随着钢板轧制厚度的增加,铸坯角部横裂纹沿宽度方向延展有加重的趋势;轧制规格相对较薄的钢板的裂纹极微小,有被"撵平"的趋势;毛边钢板的安全切边量为35mm.关键词:板坯； 角横裂纹； 切边量； 钢板边裂......
performance, segmentation analysis was performed on froth images characterized by fully occupied convex bubbles with white spots effect. An improved valley edge detection method was proposed to extract.... Key words: flotation; bubble size; valley edge detection; watershed segmentation ......
