“…Hout et al produced TiV 0.9 Mn 1.1 by ball milling [18], while Lototskyy could obtain ferrovanadium [19]. Zhang et al reported the synthesis of V-4Cr-4Ti powders by high-energy vibrating and planetary ball milling [20]. The density of dislocation of powders synthesized by planetary ball milling was much lower than in specimens produced by vibrating ball milling at a similar input energy [20].…”

Mechanochemical Synthesis and Hydrogen Sorption Properties of a V-Ni Alloy

Vanadium can store large quantities of hydrogen (about 4 mass%). However, only half of it can be reversibly absorbed. To avoid this issue, various partial substitutions were previously proposed, such as Ni. In this work, we explore the synthesis of a V85Ni15 alloy by means of ball milling, a simpler and more scalable method compared to arc or induction melting usually applied for metal alloys. After ball milling the powders of the pure metals for 15 h in argon, SEM–EDX measurements confirmed the stoichiometry of the synthesized material, which has a typical particle dimension of the order of a few microns and is composed from the coalescence of nanometric primary particles. XRD indicated a BCC crystalline structure with a typical grain size of ≈3 nm. Hydrogen can be absorbed without activation procedures at high temperatures. Up to H/M ≈ 0.08, one can observe the occurrence of a solid solution of hydrogen in the alloy, while at a higher hydrogen content, the formation of a hydride is likely to occur. The maximum hydrogen content is H/M ≈ 0.4 at the maximum investigated pressure in this study of p ≈ 45 bar. Both the hydrogenation enthalpy and entropy decrease as the hydrogen content increases, and the shape of the sorption isotherms is different from that of V85Ni15 produced by induction melting, possibly because of the nanometric dimensions of the particles produced by ball milling.

“…Indeed, the powders are formed by repeated fracturing and cold welding or agglomeration, starting typically from solid powder precursors. Common but relatively ineffective ways to affect particle sizes are to change the size of milling balls and to select process control agents (PCAs) that affect cold welding. However, particle shapes are mostly determined by mechanical properties of the material milled and evolve during milling until a steady state size is reached .…”

Microspheres with Diverse Material Compositions Can be Prepared by Mechanical Milling

et al. 2019

This study introduces a novel, simple, and scalable method of preparing spherical particles from a range of materials of potential interest in food, pharmaceuticals, energetics, and additive manufacturing. Spherical particles with dimensions in the range of ≈1–100 μm are prepared by mechanical milling of precursor materials in the presence of a blend of immiscible liquids. Microspheres of hard and ductile materials including metals (aluminum, titanium), metalloids (boron), oxides (of iron or silicon), organic compounds (melamine, sucrose), and composites (aluminum–boron, aluminum–titanium, aluminum–copper oxide, aluminum–iron oxide) were prepared. The proposed mechanism leading to the formation of spheres includes formation of a Pickering–Ramsden emulsion coexisting with a dense suspension of solids in the continuous phase. Milling continuously transfers energy to the multiphase mixture, destabilizing particles located on the liquid interface. This causes a net transport of solids from the continuous phase into the emulsion droplets where solids accumulate and form microspheres that can be recovered after milling. The process continues until the solid loading of the droplets exceeds a limit, or until the continuous phase suspension is depleted. Microspheres prepared by this method may be of interest as feedstock for additive manufacturing, for drug formulations, catalysts, membranes, and in various other technologies.
