METHOD FOR PRODUCTION OF MATERIAL FOR WEAK-CURRENT CONTACTS OF REGULATING ALLOYS ON THE BASE OF PALLADIUM Russian patent published in 1997 - IPC

Abstract RU 2083717 C1

FIELD: non-ferrous metallurgy, instrument making. SUBSTANCE: method involves production of alloy followed by its deformation with more than 80 % compression and by annealing. Said alloy is prepared of mixture which contains 24-32 mass % of Cu, 16-20 mass % of Au, 10-18 mass % of Ag and Pd. Said annealing is carried out at temperature which is lower than critical ordering temperature, heating rate being not more 30 C/min. EFFECT: improved efficiency of the method.
