【Abstract】 tructural variations within Ag sheathed superconducting Bi-2223 tapes were studied. The distribution of microhardness on cross-section area was measured. The relation between the difference of superconducting properties and deformation inhomoneity during roiling and pressing were analyzed.更多还原
