Suppression of Kirkendall porosity in multifilamentary superconducting composites

Creators

Description

The effect of hydrostatic pressure during reaction heat treatment on Kirkendall porosity in Nb/sub 3/Sn multifilamentary composites is examined. Above a critical pressure which is a function of wire size, void formation is suppressed, and at higher pressures voids already present may be healed. The critical pressure is relatively low, 300-500 psi for 0.010 inches wire, for external diffusion. 5 refs
