Abstract Scope Constantan has been widely used as a material for thermocouple because of its thermoelectric performance. Cu56Ni42Mn2 alloys have been prepared by vacuum arc melting (AM) followed by room temperature rolling (RTR) or cryorolling (CR). TEM results show that many deformation nanoscale twins in the form of bundles are detected in CR samples, whereas elongated grains parallel to rolling direction and a few twins can be acquired in RTR sample. RTR and CR can effectively decrease the thermal conductivity due to the barrier scattering by the twin boundaries and keep the high power factor. Finally, high ZT of Cu56Ni42Mn2 alloys can be achieved by cryorolling and introducing a large number of nanoscale deformation twins into microstructure.
