Abstract
A comparative study on mechanically alloyed Ag37Cu63 alloy was carried out using TEM, XRD, DSC and fractography. The amorphous phase and sup ersaturated solid solution with the initial composition in the 1 GPa s pecimen transform into Cu-8 at.%Ag solid solution, Ag- and Cu-phases d uring heating. A higher compaction pressure accelerates this transform ation. Since some of the mechanical alloying granules are composed fro m extremely small non-equilibrium grains, their melting point is about 150 degrees C, which gives a different explanation of the DSC profile s.
