Аннотация
Strain-hardening curves and the nature of deformation of YBaCuO–Ag power compounds are studied in a wide range of Ag concentration (0⩽c⩽100%) at T = 77 K. It is found that the deformation curves can be divided into four groups determined by the Ag concentration. The concentration dependences of the deformation parameters σ0, σmax, and εmax are obtained. It is shown that silver can noticeably improve the technological properties of the HTS ceramic material by varying its deformation behavior considerably.
