In this study, the reversible response of Ic with uniaxial strain in differently processed GdBCO coated conductor tapes with different substrates has been investigated under self field and magnetic field conditions at 77 K. Higher irreversible strain limit, εirr was observed in those samples with stainless steel substrate. Additional brass lamination to the Cu-stabilized samples produced enhancement of both εirr and endurable load limit. However, no significant widening of the I c/Ic0-tensile strain window with brass addition was observed in the case of samples having stainless steel substrate. Furthermore, under magnetic field, the Ic degradation behavior was independent on the kind of substrate material, but varied with the kind of manufacturing process adopted. The GdBCO samples showed different Ic peak positions and degradation behavior depending on the level of magnetic field applied.
