The simultaneous effects of milling parameters (time and balltopowder weight ratio (BPRs)) on the MM powder were investigated by FESEM and PSA. Mechanical alloying (MA) of the milled powder with 40 wt% −2 µm SiC and characterization of the obtained powder by OM and PSA were also carried out.
May 04, 2010· Commercially produced magnesium diboride powder was modified by attrition milling and ball milling in propan2ol for various durations. These powders were characterized by means of particle size distribution measurements using laser diffraction, impurity analysis using xray diffraction, energy dispersive spectroscopy and xray photoelectron spectroscopy, and scanning electron .
The lower position of magnesium in the electrochemical series will make the magnesium corrode before the steel will. Making such a block of magnesium into a fine powder will not be easy. Filing or cutting and ball milling may be tried. Ball milling of metals can be .
In 1998, Huot et al. [37] synthesized the ternary hydride Mg2FeH6 by highenergy ball milling magnesium hydride with iron, at room temperature under argon atmosphere with excellent yield.
