hydrogen evolution conditions was investigated. Copper powders were characterized by the scanning electron microscope (SEM), X-ray diffraction (XRD), particle size distribution (PSD... in the conditions of vigorous hydrogen evolution is shown. Key words: electrolysis; copper; particles; specific surface area (SSA); particle size distribution (PSD) 1 Introduction Electrolysis is widely......
of fluid dynamics and multiphase flows. Bubble size and its spatial distribution are two key factors that influence bubbly flow patterns [1, 2]. Essentially, the knowledge of the movement of even a single... J. Cent. South Univ. (2018) 25: 3021-3032 DOI: https://doi.org/10.1007/s11771-018-3971-9 Effects of initial bubble size on geometric and motion characteristics of bubble released in water KANG Can......
Effect of TiC particle size on microstructure and mechanical properties of 1%TiCp/W composites YU Fu-wen(于福文)1, WU Yu-cheng(吴玉程)1, CHEN Yong(陈 勇)1, DENG Jing-quan(邓景泉)1, CHEN Jun-ling(陈俊凌... temperature. The results show that both n-TiC and μ-TiC particles are homogeneously distributed in the as-sintered composites. The size of n-TiC particle is about 100 nm, and that of μ-TiC particle......

Article ID: 1003-6326(2005)02-0217-04 Effect of particle size on thermo-physical properties of SiCp/Cu composites fabricated by squeeze casting WU Gao-hui(武高辉), CHEN Guo-qin(陈国钦), ZHU De-zhi... applications, copper matrix composites reinforced with different sized SiC particles (10μm, 20μm and 63μm) were fabricated by squeeze casting technology. And the effect of particle size on their thermo......
were investigated. The experimental results show that, at the same process parameters, the porosity and pore size distribution of green pellets have no evident relation with the MgO bearing additive, pore size of green pellets is between 15 μm and 35 μm and the porosity of green pellets is about 34%. There is a densification and consolidation phenomenon during the induration process; the pore size......
