Anisotropic bonded magnets are fabricated by surfactant-assisted ball milling in a magnetic field and magnetic field alignment of the milled chip-like nanoparticles of the Sm–Co and Nd–Fe–B materials. It is found that the application of magnetic fields during the ball milling strengthens the anisotropy of the chips and therefore improves the alignment. For SmCo5 phase-based chips, for instance,...

magnesium is potentially useful for orthopedic and cardiovascular applications. magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it with ceramic...

Cadmium oxide has found its applications in various areas of research such as solar cells, phototransistors, photodiodes, transparent electrodes and gas sensors. In the present work CdO nano particles were successfully synthesized from cadmium acetate through thermal decomposition at high temperatures by adopting the solid state reaction. The prepared nano particles are subjected to ball millin...

In this paper, 2wt.% Fe doped TiO2 nanopowder was prepared by a combination of sol-gel and mechanical alloying methods. The mechanical alloying of Fe powder with Ti(OH)4 gel produced from the sol-gel method was used to produce Fe doped TiO2 nanopowder. The synthesized samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and diffuse reflectan...

In this work, substituted lanthanum manganites with calcium and strontium, La0.7Ca0.3-xSrxMnO3 (x = 0, 0.1, 0.2, 0.3), were prepared by a high-energy ball milling method and their microstructure and magnetotransport properties were studied. The raw materials were Mn2O3, La2O3, CaO and SrO, mixed in the stoichiometric ratio to obtain these manganites. The mechanical activation process was perfor...

A mixture of Tio2+Al+C powders was mechanically activated using a planetary ball mill under different milling conditions wherein the milled powders were further subjected to combustion synthesis to produce TiC+Al2O3 composite. The mechanically alloyed powders were characterized by X-Ray diffraction analysis and TEM investigations. XRD analysis of milled powder mixture showed no significant reac...

In this paper, the production of Al2O3-Mo nano-composites via mechanical milling was investigated. Molybdenum and alumina powders with certain ratios were grounded in a planetary ball mill at different times. XRD technique was used to determine the crystallite size of the milled powders. The microstructure of milled powders was studied using optical and electron microscopes. The crystallite siz...
