Effect of plastic deformation on electrical resistivity of molybdenum monocrystals

С. В. Пирогова, I.V. Burov, E.M. Savitskii

Abstract

The effect of crystal lattice defects, due to plastic deformation of monocrystal molybdenum, on changes in electrical resistance at 4.2 deg K was studied. For separation of the contribution of vacancies and dislocations to electrical resistance, samples were annealed at 800 deg K after deformation. It was established that the residual resistance due to vacancies in molybdenum was 4 x 10/sup -5/ ohm cm/at.% and that due to dislocations of the order of 10/sup -16/ ohm cm/sup 3/. (tr-auth)
