Effect of post annealing on phase transformation of Ni-Mn-Ga ferromagnetic shape memory alloy particles prepared by ball milling TIAN Bing(田 兵), CHEN Feng(陈 枫), LI Li(李 莉), ZHENG... annealing on the phase transformation of Ni52Mn24Ga24 ferromagnetic shape memory alloy particles prepared by ball milling was studied. Ni52Mn24Ga24 alloy particles at micron scale were prepared......
Ni(OH)2 particles synthesized by high energy ball milling LIU Yuan-gang(刘元刚), TANG Zhi-yuan(唐致远), XU Qiang(徐 强), ZHANG Xiao-yang(张晓阳), LIU Yong(柳 勇) School of Chemical Engineering and Technology, Tianjin University, Tianjin 300072, China Received 17 October 2005; accepted 6 March 2006 Abstract: High energy ball milling(HEBM) method was applied to synthesize nickel hydroxide......
Ball Milling Synthesis and Property of Nd0.7Sr0.3MnO3 ManganitesShunsheng Chen1), Changping Yang1), Lingfang Xu1) and Shaolong Tang2) 1) The Provincial Key Laboratory of Piezoelectric Ceramics..." name="ChDivSummary">Strontium doped perovskite-type Nd0.7Sr0.3MnO3 ceramics were synthesized completely by high-energy ball milling raw oxides of Nd2O3, SrCO3 and MnO2. The optimal ball milling time......
) was then filtrated, dried, and ground for use in subsequent experiment. The wet-milling pretreatment was conducted at room temperature in a ball mill using a slurry with a mixed product-to-water mass.... However, adding PEG during the wet milling of the mixed product promoted the subsequent recovery of Fe3O4. When the amount of PEG-200 increased from 0% to 4% of the powder mass, the grade of iron......
% in sinter. Key words: chromite concentrate; pellet sintering process; wet ball milling; solid diffusion consolidation; liquid phase bonding 铬铁矿是生产铬铁合金的重要原料.但是,我国铬矿资源贫乏,保有储量仅占世界储量的0.15%,95% 铬铁矿依靠进口,进口量达302万... possesses poor pelletability due to coarser size and lower specific surface areas, which can be significantly improved by finely grinding the chromite concentrate up to 1 700 cm2/g through wet ball......
Fabrication and microstructure of nanostructured Mg-3Ni-2MnO2 by ball milling in hydrogen atmosphere FANG Wen-bin(房文斌), FANG Wa(房 娃), SUN Hong-fei(孙宏飞), YU Zhen-xing(于振兴) School...; Abstract: Nanostructured Mg-3Ni-2MnO2 was synthesized by ball milling elemental powders......
Effect of ball milling on hydrogen storage of Mg3La alloy董汉武,欧阳柳章,孙泰,朱敏摘 要:Hydrogen storage and microstructure of ball milled Mg3La alloy were investigated by X-ray diffraction and pres- sure-composition-isotherm measurement. The ball milled Mg3La alloy could absorb hydrogen up to 4wt.% at 300 °C for the first time, along with a decomposing course......
