Texture formation peculiarities of zirconium in condition of large plastic deformation and its influence on characteristics of creep in the temperature ranges 300...700 K

Methods of study of a resistance, the thermo-emf, X-ray crystal analysis and optical microscopy are investigated structural peculiarities of zirconium after a strain by rolling on 92 % at 100 both 300 K and consequent annealing. It is shown, that in conditions of large plastic deformation the rolling temperature does not influence on type of the formation texture and parameters of a material microstructure. Observed increase of strength properties and creep-resistances, and also higher thermomechanical stability of the zirconium received with use of a prestrain by rolling at 100 K, is caused by peculiarities of grains boundaries structure
