Among recently found multi-component Zr-based bulk metallic glasses (BMG), Zr₅₈.₅Cu₁₅.₆Ni₁₂.₈Al₁₀.₃Nb₂.₈ is characterized by its lower critical cooling rate requirement and absence of beryllium as one of the constituent element which makes its handling more convenient. Its large supercooled liquid regions made possible the study of thermodynamics and kinetics of this...
A high temperature high vacuum rheometer has been designed, fabricated,
and tested for the study of the steady shear viscosity for multicomponent bulk
metallic glass forming alloys. This rheometer has an operating range up to
1525 K, rotational frequencies of 9.4*10⁻³-3.7*10¹ radians/s, and a
calibrated viscosity range of 9.6*10⁻³ and...
