This paper aims at examining the bending mechanical properties of MgB2/Nb/Cu wires and tapes fabricated with in situ powder in tube (PIT) method. The bending characteristics of five different MgB2 wires and tapes including four wires with mono-, 6-, 12-, and 36-filamentary and a 6-filamentary tapes were tested. The critical current density (Ic) as a function of bending diameter was measured and compared for all the prepared samples. This study aims at giving a clear picture of the optimum bending conditions at which MgB2 wires will possess a high current carrying capacity for practical applications.
► A bending test device has been developed in this work. ► The critical current density Jc is decrease with decreasing the bending diameter. ► A sharp decrease in Jc is appeared while the bending diameter small than 50 mm.
