Abstract

The effect of axial tensile strain ε applied along the conductor axis, on J_c in YBCO films deposited on buffered Ni-5W, Ni-10-at.%-Cr-2-at.%-W(Ni-10Cr-2W), and pure Ni RABiTS is presented. It is believed that the strain tolerance of these composites would be severly limited by the reltaively low yield strains of the RABiTS. The results revealed that the onset strain ε_onset where J_c(ε) first drops below its initial value is substantially higher than ε_p, indicating that fractures in the ceramic layers do not occur simultaneously with substrate yielding for these systems.
