During the manufacture of various coils, conductor wires with rectangular-shape cross section are wound to small diameter (less than 15 mm). The small diameter results in large bending strain due to the large wire thickness. In our study, the maximum bending strain even exceeded the elongation of CuAg conductor wires, which may cause premature failure. In some applications, even smaller bending diameter is requires, which then leads to even higher bending strain in conductor. Therefore we conducted ex-situ bending test on CuAg wire to compare and analyze the microstructure and strain evolution near the inner and outer side surfaces. The bendability is directly related to the ductility and work hardening of CuAg, and is restricted by the local thinning or necking.
