Abstract
Elastic properties of a niobium‐titanium‐filament copper‐matrix composite superconductor were studied experimentally at room temperature. Ultrasonic pulse and resonance measurements showed the material has orthorhombic symmetry and, therefore, nine independent elastic constants. With respect to copper, C11, C22, and C33 are about 7% lower; C44, C55, and C66 are about 15% lower; the off‐diagonal elastic constants are the same; and the bulk modulus is about 5% lower. Deviations from isotropic elastic behavior are small.This publication has 5 references indexed in Scilit:
