Hydrogen absorption–desorption properties of Mg–Ca–V BCC alloy prepared by mechanical alloying

New Mg–V–Cr BCC Alloys Synthesized by High-Pressure Torsion and Ball Milling

“…To examine the formation of MgVCr BCC alloys by other synthesizing methods, the MgVCr composition, which exhibited the best homogeneity and phase stability after HPT processing, was synthesized from the MgH 2 , V and Cr powders by high-energy ball milling. The ball milling was selected because numerous publications indicated the potential of the method for synthesizing hydrogen storage materials, 9,11,36,37) for enhancement of hydrogen storage properties 2,3,38,39) and for possible applications in industry. 4042) XRD profiles before ball milling, after ball milling for 24 h and after ball milling followed by HPT processing for 50 turns are shown in Fig.…”

Hydrogen desorption properties of MgH2–TiCr1.2Fe0.6 nanocomposite prepared by high-energy mechanical alloying

“…Many studies have been performed to improve the hydrogen absorption/desorption characteristics of MgH 2 in order to prepare an appropriate material for practical purposes at low temperatures [4]. Mechanical alloying of magnesium [5][6][7][8][9][10] and magnesium hydride [11][12][13] have been used to increase the surface to bulk ratio, induce stresses and defects in the structures, and refine the grain structure to improve the H-kinetics. Many researchers have also examined mechanical milling of MgH 2 with transition metals [14][15][16][17], intermetallic compounds [9,12,18,19], metal oxides [14,20], and graphite [21,22].…”

Synthesis, phase transformation, and hydrogen storage properties of ball-milled TiV0.9Mn1.1

“…Mechanical alloying has also been used for the synthesis of Mg-TM-V (TM: transition metals) and Mg-Co alloys with a BCC structure [20][21][22]. Kondo and Sakurai have prepared Mg-Ca-V BCC alloy by mechanical alloying of CaMg 2 and vanadium [23]. However, the hydride could only desorb at high temperature and with partial decomposition.…”
