We report measurements of the elastic properties of Zr-based bulk metallic glasses, Zr52.5Cu17.9Ni14.6Al10Ti5, Zr50Cu30Ni10Al10, and Zr50Cu40Al10 between 5 K and 300 K. Both the shear and longitudinal modulus have been measured as a function of temperature, allowing accurate determination of the Poisson’s ratio and the related ratio of bulk modulus to shear modulus, K/G. These data make it possible to assess the influence of the alloy’s composition on the mechanical properties and enable an evaluation of the correlation between the elastic moduli and the ductility of the alloys.

Elastic properties and acoustic dissipation associated with the disorder–order ferroelectric transition in a single crystal metal–organic framework (MOF), [NH4][Zn(HCOO)3], have been investigated using resonant ultrasound spectroscopy (RUS) in the temperature range between 10 K and 300 K.
