ABSTRACT:
Alloys of the atomic composition, Ag.sub.(25-66) Cu.sub.(16-68) In.sub.(7-18) in the form of thin foil, are made ductile by the presence of appreciable amounts of amorphous phase and a metastable, micro-crystalline, solid solution, single phase and are especially suited for fabricating preforms for preplacement in a joint to be joined by an operation such as brazing.
