The superconducting critical current I/sub c/ (4.2 K) of V/sub 2/(Hf,Zr) composite tape was measured under tensile load. I/sub c/ values of the V/sub 2/(Hf,Zr) composite tape do not change at all up to a strain level of 0.55%, and then decrease irreversibly with respect to strain, although the stress-strain curves for these tapes exhibit no irreversible behavior. Many cracks were observed in the V/sub 2/(Hf,Zr) layer of the composite tape strained up to 0.6%. Thermal expansion data indicate that the residual tensile stress may be produced in the V/sub 2/(Hf,Zr) layer by the large thermal contraction of the layer and may reduce the strain tolerance of the composite tape.
