In order to elucidate the strain dependence of superconducting properties of REBCO coated conductors, which show complicated strain dependence originating from existence of twin structures, we tried to control the domain structure by using a high-temperature-bending annealing method and investigated superconducting properties, such as critical current density and critical tempereture, under external in-plane uniaxial strains.
