Mechanical milling of aluminum powder using planetary ball milling process
Mechanical alloying has recently attracted considerable attention as researchers strive to enhance nanocomposite properties and extend their utility. The process can be performed at room temperature and homogeneous nanocomposite powders can be produced. In this paper, we investigated the effect of different ball milling parameters and operating conditions (milling time, ball size, processing co...
متن کاملFlux Pinning Optimization of Bulk Samples Prepared Using High-Energy Ball Milling and Addition of
is considered to be an important conductor for applications. Optimizing flux pinning in these conductors can improve their critical currents. Doping can influence flux pinning efficiency and grain connectivity, and also affect the resistivity, upper critical field and critical temperature. This study was designed to attempt the doping of on the Mg sites with metal-diborides using high-energy ba...
متن کاملPhonon density of states of nanocrystalline Fe prepared by high-energy ball milling
We performed inelastic neutron scattering measurements on nanophase Fe powders prepared by high-energy ball milling. Neutron energy loss spectra were measured for two states of the material: ~1! as milled, when the material had a characteristic nanocrystallite size of 12 nm; and ~2! annealed, when the material had a characteristic crystallite size of 28 nm. The longitudinal peak in the phonon d...
متن کاملIon Transport Properties of the Inverse Perovskite BaLiF3 Prepared by High-Energy Ball Milling
For many applications such as advanced energy storage systems, chemical sensors or electrochromic devices fast ionic conduction plays an important role. In many cases, see e.g., Refs. [1-3], nanocrystal-line ceramics with crystallite diameters smaller than 50 nm show an enhanced ion conductivity compared to their coarse-grained counterparts, i.e., single crystals or materials with µm-sized part...
متن کاملAtomic-scale structure of nanocrystalline ZrO2 prepared by high-energy ball milling
The atomic-scale structure of nanocrystalline ZrO2 obtained by ball milling has been studied using highenergy x-ray diffraction and the atomic pair distribution function technique. The studies show that, upon relatively short milling times, the parent crystalline material, monoclinic ZrO2, evolves into a nanocrystalline phase that is locally similar to monoclinic zirconia but shows a cubic-type...
