We have developed BaHfO3 (BHO)-doped EuBa2Cu3Ox (EuBCO) coated conductors (CCs) using a hot-wall type pulsed-laser-deposition (PLD) with a high throughput condition on ion-beam-assisted-deposition (IBAD) template with a thickness of 50 μm including Hastelloy substrate. Although we have investigated the in-field Jc properties, mechanical properties are also one of the most important issues for high field magnet applications. In this article, we investigated the degradation characteristics of REBa2Cu3Ox (REBCO) CCs including the BHO-doped EuBCO CCs under uniaxial tensile strain and bending strain. As a result, dependences of irreversible strain on the REBCO film thickness were clarified. In addition, longitudinal fatigue properties of the CC were investigated by repeated tensile tests, and a fatigue behavior of metallic components of the CC was confirmed in more than 100 000 cycles.
