High-Energy Ball-Milling of Alloys and Compounds
Hyperfine Interactions, 2002After outlining some characteristics of high-energy ball-milling, we discuss selected examples of phase transformation and of alloy synthesis which focus on deviations from archetypal behaviours and throw light on the milling mechanisms. Some contributions of Mossbauer spectrometry to the characterization of ground materials are described.

In this paper, copper matrix nanocomposites reinforced by 5, 10 and 15 wt% ZrO2 particles were produced using high energy ball milling technique with different milling time. The optimum milling time is predicted analytically and validated experimentally.

Photocatalytic antibacterial properties of copper doped TiO2 prepared by high-energy ball milling
Ceramics International, 2020TiO2 nanopowders and Cu-doped TiO2 were prepared by high-energy ball milling and characterized by X-ray diffraction (XRD), UV–vis diffuse reflectance (UV–vis - DRS) spectra, a scanning electron microscope (SEM), an energy dispersive spectrum (EDS) and an

Hydrogenation of TiFe by high-energy ball milling
Journal of Alloys and Compounds, 2000The hydrogenation properties of TiFe, TiFe2 and pure Ti during high-energy ball milling in hydrogen atmosphere were studied. By ball milling, TiFe could absorb hydrogen without activation treatment. For Ti powder, a single phase TiH1.924 was formed.

High energy ball milling of Co89B11 powders
Nanostructured Materials, 1999Abstract Mechanical alloying was performed on elemental cobalt and boron powders with atomic ratio Co 89 B 11 . X-ray diffraction analysis (XRD) and differential scanning calorimetry were used to characterize the structure of the milled samples before and after the heating. The high-energy ball milling was found to influence the resulting phases. The

Synthesis of Cu–W Nanocomposite by High-Energy Ball Milling
Journal of Nanoscience and Nanotechnology, 2007The Cu-W bulk nanocomposites of different compositions were successfully synthesized by high-energy ball milling of elemental powders. The nanocrystalline nature of the Cu-W composite powder is confirmed by X-ray diffraction analysis, transmission electron microscopy, and atomic force microscopy.

DEM Modeling and Optimization of the High Energy Ball Milling
DESIGN, CONSTRUCTION, MAINTENANCE, 2022The Discrete Element Method (DEM) is a numerical method for simulating the dynamics of particles processes. This present work focuses on DEM simulations of a scale laboratory planetary ball mill through DEM Altair 2021.2 software to optimize and modulate the milling parameters. The simulation results show a good agreement with the experiments.
