Practically, coated conductor (CC) tapes are apt to be exposed to external magnetic fields, hoop stress, and other inevitable stress- and strain-producing factors during fabrication and cool-down and under operating conditions. In addition, the issue on the strain effect on the Ic degradation of REBCO CC tapes under magnetic field is not yet completely understood. In this paper, further investigation on the electromechanical response of CC tapes under magnetic field conditions was conducted. Differently stabilized CC tapes by Cu lamination and by addition of external brass lamination with different substrate materials were investigated. The Ic degradation behaviors at respective magnetic field intensity and against uniaxial tensile strain induced were reported. As observed, magnetic field dependence of Ic is not affected by macroscopic strain within the reversible strain region. Ic degradation behavior with strain was almost constant for all samples from self-field up to 0.5 T. In addition, the macroscopic pinning force and the irreversibility field were calculated and extrapolated, respectively, to investigate the effect of strain.
