โฆ Synopsis
Superconducting state stability monitored during cyclic loading under uniaxial tension has been used to study training of short specimens of the superconducting composites Cu-Nb (prepared in situ by wire drawing of the alloy Cu-40 wt% Nb) and commercial composites Cu-NbTi and bronze-Nb3Sn. Instabilities of the superconducting state were indicated by jumps of the trapped magnetic flux.

A common thread joining many engineered materials used dominantly under compressive loading is the presence of a high modulus secondary phase, either fiber or particulate, embedded within a lower modulus matrix phase. To improve their toughness, a frictional or a less-than-coherent interface is stri
