    The effect of ball milling on the melting behavior of Sn

    Sn-Ag-Cu (SAC) solder alloys are the best Pb free alternative for electronic industry. Since their introduction efforts are made to improve their efficacies by tuning the processing and composition to achieve lower melting point and better wettability. Nanostructured alloys with large boundary content are known to depress the melting points of metals and alloys.

    Mar 01 2000 · 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 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.
