High Temperature Deformation Behavior of YBa2Cu3O6+x Superconducting Ceramic Materials

Abstract

Superplastic deformation is being explored as a means to turn the new ceramic superconducting YBa2Cu3O(6+x) into useful Naval hardware. The deformation experiments hat were conducted on fine YBa2Cu3O(6+x) powders suggest that the maximum deformation that can be achieved without the degradation of superconductivity is about 62 % at 850 deg C. The addition of silver improves the maximum deformation and the addition of alumina has a devastating effect on the deformation mode.
