Abstract

In this paper, the relationships between transport J c , the core density and texture are systematically studied by fabricating silver sheathed Sr 1−x K x Fe 2 As 2 superconducting tapes with different thickness. The cores densities increase when the tape thickness decreases to 0.5 mm. But the core density of 0.4 mm tapes is the same with that of the 0.5 mm ones as the core density has been saturated in such rolling deformation. However, there is a positive correlation between the transport J c and texture of superconducting tapes. We conclude that the core density and the texture have a combined influence on the final performance of tapes and the J c of iron-based superconducting tapes can be further improved by increasing the texture degree when the core density saturated within the experimental conditions.
