Neutron-diffraction analysis and measurements of electrical resistance were used to investigate the kinetics of ordering in Ni3(Mn, Cu) alloys preliminarily tempered at 900°C, containing 0.45-9.29 at.% copper. It was established that introducing copper atoms in place of manganese atoms in the alloy Ni3Mn leads to slowing of the ordering process. The degree of long-range order inside antiphase domains in Ni3(Mn, Cu) alloys is less than in the binary alloy.
