The thermoelectromotive force and electrical resistivity of the polycrystalline hafnium (Hf) with the grain size of 10 {\mu}m during the process of plastic deformation in the regime of creep at the temperature of 300 K are precisely measured. It is shown that the thermoelectromotive force depends on the deformation mechanism nature, because of the changing magnitude of the electrons scattering on the different structural defects in the hafnium crystal lattice at the deformation process. The main research conclusion is that the method of thermoelectromotive force measurements is more informative, comparing to the method of electric resistivity measurements in the process of accurate characterization of the hafnium.
