| 中文摘要 | We find that a family of CeAlNiCu alloy system can be readily cast into bulk glassy rods with up to 3 mm diameter. The Ce-based bulk metallic glasses (BMG's) exhibit a wide supercooled region up to 78 K, very low glass transition temperature (T(g)=359 K), and Debye temperature (theta(D)=144 K). The glass formation, crystallization, glass transition, liquid behavior, and elastic and acoustic properties of the CeAlNiCu alloys are investigated. Ultrasonic measurements demonstrate that the Ce-based BMG's are the softest in elastic moduli in known BMG's due to their very low glass transition temperature. The fragility parameter (m) is determined to be 21, indicating the strong liquid behavior of the alloy concerning the temperature dependence of viscosity. A remarkable large softening of long-wavelength acoustic phonons in the BMG relative to its crystalline state is observed, and the phonon softening is attributed to its intrinsic microstructural features and strong liquid behavior. |
