The electro-mechanical characteristics of the nickel sheathed powder-in-tube MgB2 mono-core tapes with 10 vol% indium powder were evaluated. No marked change in the stress-strain curve was found by indium addition. On the other hand, the irreversible strain for the tape where a drastic degradation of critical current Ic begins increased from 0.25% to 0.50% by the addition of indium. The indium addition also suppressed the slight increase in Ic with strain. These characteristics of Ic with strain were compared with those reported by other researchers. Scanning electron microscope observations of the longitudinal section of degraded samples revealed that the number of micro-cracks was appreciably smaller in the indium added tapes.
