We present a study of nanostructured Cu-Ag material obtained by low temperature ball milling. The microstructural characterization is carried out using a wide variety of transmission electron microscopy (TEM) techniques from conventional dark-field imaging, selected area diffraction and energy dispersive X-ray spectrometry (EDS) to more modern techniques of scanning TEM high-angle dark-field ...

The temperature obtained during cryo- ondly, while Cu and Ag are immiscible in the solid milling was estimated to be 85 K by Klassen et al. state at equilibrium, a complete nanostructured [19]. Thereafter we refer to this temperature as solid solution is obtained after ball milling at 85 LN2.

A TEM and STEM investigation of Cu-Ag nanomaterials synthesized by temperature controlled high-energy ball-milling more by Slim Zghal It is well documented that low-temperature ball-milling can force immiscible elements, e.g., Cu and Ag, into solid solution.

Electron microscopy nanoscale characterization of ball ...

The Cu–Ag alloy system has been selected for this study for several reasons. Firstly, both Ag and Cu have low stacking fault energies, 16 and 45 mJ/m 2, respectively . Little recovery should therefore take place during low temperature ball milling as it is similar to an intense cold-working, opening the possibility of stabilizing highly ...

Sn–Ag–Cu (SAC) powder: P7(int-5); RT milling. The X-ray diffraction patterns for different milling times are shown in Fig. 1a and the relevant phases for the corresponding Bragg reflections are indicated on the plot. The patterns exhibit well-defined Sn peaks of tetragonal structure and weak reflections from Ag 3 Sn. It can be observed that the peaks were broadened with continued milling ...

It is well documented that low-temperature ball-milling can force immiscible elements, e.g., Cu and Ag, into solid solution. A slight increase of the milling temperature however results in a two- or even three-phase coexistence [1]. This coexistence is likely to take place at a nanometric scale since ball-milling results in the formation of grains with a size in the 10 nm range.

Solubility Study in Ag-Cu Binary System Prepared By Ball ...

Solid solutions of Ag-Cu were prepared via ball milling process, for about 5-30 h. The Cu-20at%Ag and Cu-3.64at%Ag composition were investigated by X-ray diffraction technique. It was realized that the solid solubility level could be increased by increasing the initial solute content in the mixture. In addition, shifts in peak positions
