Summary

THE EFFECT OF UNIDIRECTIONAL AND SIGN-VARIABLE TORSIONAL STRAIN AT 4.2 K ON THE TEMPERATURE OF THE SUPERCONDUCTING TRANSITION T IN VANADIUM IS STUDIED. THE T RISE IS REVEALED TO BE A NON-MONOTONIC FUNCTION OF THE DEGREE OF STRAIN: AT THE BEGINNING T RISES SHARPLY AND THEN DECREASES GRADUALLY, THOUGH REMAINS HIGHER THAN THE INITIAL VALUE UP TO THE SAMPLE FRACTURE. AT THE INITIAL STAGES THE VANADIUM DEFORMATION IS CAUSED BY MECHANICAL TWINNING. IT IS CONCLUDED THAT THE RISE OF VANADIUM T RESULTS FROM TWIN INTERLAYERS OF HIGH COMPRESSIVE STRESSES IN THE VICINITY OF THEIR BOUNDARIES, WHICH APPEAR IN THE PROCESS OF LOW-TEMPERATURE DEFORMATION.
