University, Changsha 410083, China; 2. Hunan Research Institute of Nonferrous Metals, Changsha 410015, China) Abstract: Indium tin oxide(ITO) aqueous suspension was prepared through ball milling dispersion using Methyl cellulose (MC) as dispersant. The effects of MC dosages , ITO content and ball milling dispersion time on stability of ITO aqueous suspension were investigated．And the functional......

The morphology transformation of carbon nanotubes during ball milling process was observed by SEM and TEM, respectively. The results show......
Effect of ball milling time on microstructures and mechanical properties of mechanically-alloyed iron-based materials LIU Dong-hua(刘东华), LIU Yong(刘 咏), ZHAO Da-peng(赵大鹏), WANG Yan(王 岩... of 10 mm and 6 mm, respectively. The ball-to-powder mass ratio (BPR) was 8?1. The rotation speed was 225 r/min, and the milling time of 100, 144 and 200 h was adopted, respectively. Powder handling......
under a purified argon atmosphere for 5 h. The mass ratio of ball to powder was 20:1 and the milling rotation speed was 300 r/min. The as-milled powder was heat-treated at various temperatures for 30.... The phase changes due to ball milling and subsequent heat treatment were characterized by X-ray diffraction(XRD) using Cu Kα radiation. Particle sizes of alloy powder were measured with an atom......
Effect of ball milling time on microstructure and properties of Laves phase NbCr2 alloys synthesized by hot pressing XIAO Xuan(肖 璇)1, 2, LU Shi-qiang(鲁世强)1, HU Ping(胡 平)1, HUANG Ming-gang(黄铭刚)1... alloys, prepared from elemental niobium and chromium powders under various ball milling time by hot pressing at 1 250 ℃ for 0.5 h, were investigated. The results indicate that if the ball milling time......
composites can be reduced to 50-100 nm by dry ball-milling, which may play a partial role in improving the hydriding/dehydriding kinetics. References [1] BOGDANOVI? B, SCHWICKARDI M. Ti-doped alkali... in improving the hydriding/dehydriding kinetics.

portion is 2 mm. A double-flute (two-flute) cylindrical ball head end milling cutter with a helix angle of 20° and an front angle r0 of 5° is used in the milling process. The tool diameter is (equal to) 5... the tool path is generated. Since the cutting allowance of the blade finishing is small, the ball head milling cutter with a radius of 5 mm is used for milling. The residual height parameter is set to 0.01......
