FIELD: non-ferrous metallurgy; methods of changing structure of palladium-based ordered alloys; production of contact materials for resistor shutters. SUBSTANCE: proposed method includes plastic deformation by more than 80% followed by annealing performed at temperature above critical ordering temperature at rate of heating more than 100 C/min and continued for no more than 15 min. Selection of different parameters of treatment of alloy (change of degree of preliminary plastic deformation, temperature and duration of annealing, rate of heating) makes it possible to obtain material at electrical resistance not higher than 12x10-8 ohm.m in range of temperatures up to 600 C. EFFECT: enhanced efficiency. 1 dwg, 1 ex
