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.
