Vk. Aksyonov et al., THE INFLUENCE OF PLASTIC STRAIN AT 4,2-K ON THE STRUCTURE AND SUPERCONDUCTING TRANSITION-TEMPERATURE OF ZIRCONIUM, Fizika nizkih temperatur, 19(11), 1993, pp. 1187-1190
The effect of tension deformation at 4,2 K with subsequent warming to
room temperature upon the defective structure and the superconducting
transition temperature T(c) of electron-beam melted zirconium is studi
ed. The appreciable increase in T(c) (be 20%) is due to enhanced super
conductivity at the sites of localized plastic strain al the twin boun
daries and is connected with the effective change of the electron attr
action constant.
