Summary: In this study, Al2O3-10 wt% Fe composite powders were prepared by mechanical alloying with different milling times. The morphology, structure, and magnetic properties were investigated through SEM, XRD, Modssbauer spectroscopy, and magnetic measurements. The results showed a reduction in particle size, crystallite size, and an increase in lattice micro-strain, as well as the presence of a superparamagnetic component.

Summary: The effect of high-energy ball-milling on a Ni45Co5Mn35Sn15 alloy has been analyzed, showing promotion of martensitic transformation and appearance of non-transforming regions, correlated to internal strains. These mechanically-induced defects mainly lead to a reduction in magnetic moments.

Summary: Starting from micrometric pure nickel powder, high-energy ball milling process and Spark Plasma Sintering technique allow the production of dense nanostructured materials. Milling under argon confinement limits the surface oxidation of particles, providing a nanostructured dense material with a significant improvement of true ductility.

Summary: This study investigated the effects of high energy ball milling on mineral pigments using malachite and turquoise as examples. The results showed that milling reduced the size and distribution of mineral particles, reaching an amorphous state with changes in crystalline state. Valency, atomic abundance, luminance, reflectivity, and chromaticity of the milled samples all showed various changes affected by crystallinity and grain size.

Summary: High-energy ball milling was used to modify the nanoparticle size of TiO2 and study its effects on structural, microstructural, and optical properties. Increasing milling time resulted in smaller particle sizes, broadening of X-ray diffraction peaks, decreased reflectance in UV-Vis spectra, and a decrease in bandgap transition energy. SEM analysis also showed a more homogeneous distribution of nanoparticle size with longer milling duration.

Summary: This study investigated the effects of liquid process control agents (PCA) on the properties of milled powders during high-energy ball milling. Correlations between different PCA properties and milling outcomes were identified. It was found that PCA density had an impact on particle and crystallite sizes, but its effect was less significant compared to other parameters. Particle size was strongly correlated with PCA proton affinity and surface tension for Bi2O3 and CuO, respectively, while crystallite size was most strongly correlated with PCA dynamic viscosity and density for Bi2O3 and CuO, respectively.

Summary: M-type hexaferrite PbFe12O19 nano-crystallites with an average diameter of 68 nm were synthesized via high energy ball milling method. The XRD analysis confirmed the single-phase magnetoplumbite structure, and dielectric studies revealed ferro- to antiferro- and antiferro- to paraelectric transitions. Room temperature Mössbauer spectrum showed five Zeeman splitting patterns corresponding to different iron ion sites.

Summary: This study presents a simple method for synthesizing pure hexagonal Y-type hexaferrite using high-energy ball milling and low-temperature heat treatment. The effect of nickel doping on the magnetic, dielectric, and magnetodielectric properties is investigated. The results show that nickel doping reduces the specific magnetization, changes the magnetic thresholds of the magnetic phases, and increases space charge polarization. The magnetodielectric measurements also reveal different positive magnetocapacitance behaviors related to the effect of doping on the magnetic and electronic structure.

Summary: This study aimed to improve the productivity of nanobiochar (NBC) through high-energy ball milling, finding that using grinding media with different sizes of steel balls was more effective. Results showed that 30 minutes of ball milling could produce NBC particles around 95 nm, while 60 minutes were sufficient to produce 75 nm NBC particles with high thermal stability.

Summary: In this study, nanocrystalline Fe60Al40 powders were synthesized through high-energy planetary ball milling under an inert argon atmosphere. The structural, morphological, and magnetic properties of the ball-milled powders were investigated using XRD, SEM/EDX, TEM, and VSM. The results showed the formation of a disordered α-Fe(Al) solid solution with a bcc crystal structure after 14 hours of milling. The milled samples exhibited soft-hard ferromagnetic behavior, with the magnetic parameters being highly dependent on the milling time.

Summary: Through the investigation of Fe15Co2P3 powder mixture's mechanical alloying process, it was found that the crystallite size reached 100 and 200 nm after 3 hours of milling. The mechanical properties revealed the brittleness of the alpha-Fe(P) solid solution compared to the Co75Fe25 phase. In terms of magnetic properties, the hysteresis loss energy and maximum permeability of the milled powders reached minimal values after approximately 1 hour.

Summary: Research has shown that pure SnSe polycrystalline materials prepared by high-energy ball milling exhibit a high ZT value at 873K. The decrease in lattice thermal conductivity and increase in Sn vacancies induced by high-energy ball milling contribute to the improved conductivity of the materials. The absence of oxidation during the ball milling process in a closed argon-filled environment ensures the purity of the SnSe polycrystalline materials, leading to their high ZT value.

Summary: This study reports the process to fabricate powder of high-entropy carbide (TiTaNbZrHf)C using two-step high-energy ball milling. The high-entropy carbide phase was obtained through milling metallic precursors and carbon, showing thermal stability up to 1200 degrees C. The process includes the conversion of metallic precursors, the reaction diffusion of carbon, and the formation of high-entropy carbide phase from high-entropy alloy and carbon.
