In this study, the elastic properties of a hexanary high-entropy alloy superconductor were investigated at different temperatures. The results showed that the material exhibited excellent elastic performance at room temperature and even better performance at cryogenic temperature.
We report a comprehensive study on the elastic properties of a hexanary high-entropy alloy superconductor (ScZrNbTa)(0.685)[RhPd](0.315) at room and cryogenic temperatures, by Resonant Ultrasound Spectroscopy exper-iments. The derived elastic constants are bulk modulus K = 132.7 GPa, Young's modulus E = 121.0 GPa, shear modulus G = 44.9 GPa, and Poisson's ratio nu = 0.348 for room temperature. The Young's and shear moduli are similar to 10% larger than those in NbTi superconductor with similar Tc, while the ductility is comparable. Moreover, the mechanical performance is further enhanced at cryogenic temperature. Our work confirms the advantageous mechanical properties of high-entropy alloy superconductors and suggests the application prospects.
