ABSTRACT:
Nickel-Chromium-Silicon alloys of the nominal composition, Ni.sub.(45-78) Cr.sub.(16-34) Si.sub.(6-21) in the form of thin foil are made ductile by the presence of appreciable amounts of an amorphous phase and a metastable, solid solution, microcrystalline single phase and are especially suitable for preplacement as preforms in a joining operation such as brazing. Up to abour 40 atomic percent of the nickel is replaceable with palladium.
