Measuring the impact velocities of balls in high energy mills
Materials Science and Engineering: A, 1994A simple methodology for the experimental determination of impact velocities in ball mills used for the synthesis of nanophase materials is proposed. The impact velocity of the balls relative to the vial wall is determined from the indent size. A model correlating velocities with indent radius is described. Velocities were determined for the Spex mill (

Preparation of MgTiO3 ceramics by high energy ball milling
Journal of Wuhan University of Technology-Mater. Sci. Ed., 2006MgTiO3 precursor was mechanochemically synthesized by high-energy ball milling of MgO and TiO2. The sintering characteristic of the resulted MgTiO3 precursor was investigated. The experimental results indicate that particles of both MgO and TiO2 powders become smaller rapidly, and then the crystalline structures of MgO and TiO2 change significantly ...

High-energy ball milling of nonstoichiometric compounds
Uspekhi Fizicheskih Nauk, 2019Abstract The preparation of nanocrystalline powders of nonstoichiometric compounds such as carbides and oxides by high-energy milling is considered. The modern state of milling models for nonstoichiometric compounds is described. The influence of nonstoichiometry on the particle size of the produced nanopowders is discussed. The model

High-Energy Ball Milling of Some Intermetallics
Hyperfine Interactions, 2001High-energy ball milling of metallic powders has been used in recent years for the synthesis of alloys through reactions mainly occurring in solid state. The diffusive phenomena accompanying and promoting the reactions of formation are related to the microstructure acquired by the powders as a consequence of the intense mechanical deformations.
