The effect of MgNi2 intermetallic compound on nanostructurization and amorphization of Mg–Ni alloys processed by controlled mechanical milling

Controlled mechano-chemical synthesis of nanostructured ternary complex hydride Mg2FeH6 under low-energy impact mode with and without pre-milling

“…The ball milling was carried out in the magneto-mill, Uni-Ball-Mill 5 (A.O.C. Scientific Engineering Pty Ltd., Australia) [15][16][17][18][19]. As shown in Fig.…”

Nanocrystalline and non-crystalline hydrides synthesized by controlled reactive mechanical alloying/milling of Mg and Mg–X (X = Fe, Co, Mn, B) systems

“…More extensive details of milling procedures can be found in a number of Refs. [11][12][13][14][15]. Morphological and microstructural examination of powders was conducted using high-resolution, field emission SEM (FE SEM) LEO 1530 equipped with integrated EDAX Pegasus 1200 EDS/OIM and X-ray diffraction [11][12][13][14][15].…”

“…[11][12][13][14][15]. Morphological and microstructural examination of powders was conducted using high-resolution, field emission SEM (FE SEM) LEO 1530 equipped with integrated EDAX Pegasus 1200 EDS/OIM and X-ray diffraction [11][12][13][14][15]. Thermal behavior was investigated by DSC, TGA [13][14][15] and temperature programmed desorption (TPD) [14,15].…”

Formation and environmental stability of nanocrystalline and amorphous hydrides in the 2Mg–Fe mixture processed by controlled reactive mechanical alloying (CRMA)

“…The powder designated MFT (M: Mg; F: Fe and T: toluene) was initially mechanically pre-alloyed for 10 h under argon with the addition of a few drops of toluene, which served as a lubricant to prevent the ductile Mg powder adhering and cold-welding to the balls and the vial wall. Subsequently the MFT powder was mechanically alloyed under hydrogen using controlled low-energy shearing mode, in a Uni-Ball-Mill 5 which allows adjustment of any type of milling mode by changing the angular position of strong NdFeB external magnets [8][9][10][11][12]. The reactive milling time was 24 and 46 h. This batch of MFT powder milled under hydrogen is designated MFTH (H: hydrogen).…”

“…In this magneto-mill the trajectories of the steel balls are controlled by a strong magnetic field provided by the NdFeB external magnets [8][9][10]. The milling modes can be easily adjusted from low-energy shearing to high-energy strong impact as described in a couple of recent publications where the Uni-Ball-Mill 5 was applied to the mechanical milling of Mg-Ni hydrogen storage intermetallic alloys [11,12].…”
