Popis: Tensile stress experiments were made on single Ti 39.5 at % Nb fibers, 18.3 µm in diameter, and fiber bundles chemically extracted from a commercial superconducting composite. As the temperature decreases, the fracture stress increases, as does the fracture elongation. This abnormal behavior argues for either a very fine-scale structural change or microdeformation. Load-strain serrations, previously reported, were not observed in these small-diameter fibers.
