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... July 2007; accepted 10 September 2007 Abstract: The nano-TiCp/W and micro-TiCp/W composites containing 1% TiC(mass fraction) particles with average particle sizes of 50 nm and 1.5 μm were fabricated......
energy grain boundaries [21]. Under the condition of aggregation, two or more solid particles in contact with each other form a new solid particle with large size and irregular shape. It is evident...; recrystallization; partial melting; cyclic closed-die forging; spheroidization; aggregation 1 Introduction Semi-solid processing was established as a high-volume, near-net shape manufacturing process for components......
J. Cent. South Univ. Technol. (2011) 18: 1579-1588 DOI: 10.1007/s11771-011-0875-3 Power system stabilizer design using hybrid multi-objective particle swarm optimization with chaos Mahdiyeh... system stabilizer (PSS) was proposed, by integrating the modified particle swarm optimization (MPSO) with the chaos (MPSOC). Firstly, a modification in the particle swarm optimization (PSO) was made......
declines within the first 14 s, then, the temperature quickly is recovered and oscillated after 60 s. Key words: aggregation; alumina dissolution; heat transfer; mass transfer; particle size distribution... Distribution of alumina particle 表4 筛余率计算 Table 4 Calculation of sieve residue rate 3.2 下料后初始氧化铝颗粒分布 实际铝电解槽中加入的氧化铝颗粒数以亿计,目前数值模拟还远达不到此计算要求,因此,需要对氧化铝颗粒数进行合理简化,用一个氧化铝计算颗粒代表一定数目的实......
