  • A TEM and STEM investigation of Cu-Ag nanomaterials

    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.
