Ag 50 Cu 50 alloys were prepared by high-energy ball milling at 393, 423, and 453K. Atom probe tomography was used to characterize the microstructure and the local composition of the milled powders. The dynamical competition between the atomic mixing forced by milling and the phase separation promoted by thermodynamic driving forces results in the self-organization of the microstructure...
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 material first decomposes...
