Abstract
The elastic constants of polycrystalline Nb₃Sn were determined as a function of temperature when the samples were submitted to uniaxial tensile stress. The Young’s (E) and shear (G) moduli were obtained from an ultrasonic pulse transmission technique in the range 4–300 K. Their behavior with temperature and applied stress is discussed in terms of the martensitic phase transformation occurring at ∼43 K and the ferroelastic character of the tetragonal phase (T <43 K). Uniaxial tensile stress is found to stiffen the moduli at all temperatures by stabilizing the crystal structure and by progressively eliminating the domains in the tetragonal phase.
