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......

powders exist in the form of an amorphous phase which has the crystallinity lower than 30.4%, and the particle size of boron powder decreases with an increase of the high-energy ball milling rate. The purity of amorphous boron powder is 94.8% and particle sizes are much smaller than 100 nm when the mass ratio of B2O3/Mg/KClO3 is 100:105:17 and the ball milling time is 20 min with the milling rate......
Effect of ball milling process on the microstructure of titanium-nanohydroxyapatite composite powderPANG Pengsha1, 2), LI Wei1), and LIU Ying1) 1) Department of Materials Science and Engineering... heat. XRD and SEM were performed for characterization of the microstructure, and the homogeneity of Ti/HA nanocomposite powder was evaluated by EPMA with prolonged ball milling time. The results show......
Behavior of Fe Powder During High-Energy Ball Milling Cooperated with Dielectric Barrier Discharge PlasmaLeyang DAIMarine Engineering Institute, Jimei University摘 要:In this study, nanostructured Fe powders were synthesized following 10 hours of high-energy ball milling with a superimposed dielectric barrier discharge plasma (DBDP). The mean size......
