Abstract
The effect of the uniaxial tensile stress on the critical‐current density Jc, and upper critical field Hc2, of in situ formed Cu‐V3Ga composites has been investigated. Jc was found to gradually decrease at stresses greater than ∼200 MPa. The effect is small, amounting to a decrease of only 20% at 16 T and 1 GPa. However, no permanent degradation was observed even at stress levels in excess of 1 GPa. Similarly, Hc2 was found to be rather insensitive to applied stress. The observed decrease of about 0.5 T at 1 GPa was fully recovered after releasing the stress.Keywords
