— The solid state reactions induced by high-energy ball milling of Al/Ni elemental mixtures at 25, 33, 50, 67 and 75 Ni at.% have been studied by X-ray diffraction and electron microscopy.
Ag 50 Cu 50 alloys are prepared by high energy ball milling at different controlled temperatures, 85 K, 315 K and 453 K, with milling times long enough to reach steady-state. Atom probe field ion microscopy (APFIM) is used to characterize the atomic mixing forced by low temperature milling and to study the nanocomposite materials stabilized by …
— It has been reported that mechanical milling of an Ag-Cu system produces a complete solid solution for the entire composition [11][12][13] [14] [15]; hence, Ag-Cu particles were mechanically ...
— This is also supported by the measured K D of 0.054 ± 0.002 s −1 for the 4-h-milled Cu(OD) 0.8 Ag 0.2 (Supplementary Fig. 20), indicating its weak CO adsorption sites are more than those of Cu ...
— Abstract The effect of ball milling powder mixtures of Höganäs pre-alloyed iron Astaloy CrM, low-carbon ferromanganese Elkem, elemental electrolytic Cu and C-UF graphite on the sintered structure and mechanical properties was evaluated. The mixing was conducted using Turbula mixer for 30 minutes and CDI-EM60 frequency inverter for …

— Fe powders were mechanically processed by ball milling. The average size of coherent diffraction domains and the average strain content were determined by X-ray diffraction. A mathematical model was developed to describe the microstructural refinement process as a function of the number of collisions and to estimate the amount of powder …
— Ball milling of Cu and Ag powders was performed in a SPEX 8000 shaker mill following the procedure used by Klassen and coworkers [5]. ... (SAED) may also be used to extract local texture in materials. Zghal et al. reported deformation texture in Cu-Ag ball milled powders by analyzing the SAED pattern of powders [16,17]. Boulay et.al used …

— Commercially pure copper and silver powders were combined to obtain an average molar composition of 90% Cu and 10% Ag and then subjected to high-energy ball milling using a SPEX 8000 mill in an argon glove box for 12 h at ambient temperature (∼50 °C).Ball milling forces the mixing of Cu and Ag into a solid solution [23].The ball-milled …
— Cu-Ag alloys in three different compositions (Cu – 25/50/75wt% Ag) were produced by powder consolidation followed by high-pressure torsion. Deformation was performed till a saturation regime was reached. The generated microstructures were investigated by transmission electron microscopy and vary from ultra-fine grained to …
Microstructures and phases stabilized at steady state by variable temperature ball milling of Cu 50 Ag 50 powders are characterized using transmission and scanning transmission electron microscopy. Starting from chemically mixed and cold-worked powders obtained by room temperature milling, it is shown that, upon increasing the milling temperature, the …
