Abstract:: A Bulk Metallic Glass (BMG) is an amorphous solid with thickness greater than 1mm. Material properties of BMG, like twice the strength of regular steels and excellent corrosion resistance, make them ideal materials for fabrication of MEMS and MECS devices which have attracted a lot of research activity recently. Diffusion...

Abstract:: By the investigation of the bulk metallic glass-forming liquids that have very low critical cooling rates, the thermodynamics of metallic glasses can be clarified. For studying thermodynamic properties, such as the specific heat capacity, calorimetry (DSC) is utilized and one of the most used instruments is the differential scanning calorimeter....

Creator:: Shadowspeaker, Ludi A.
Abstract:: The heating rate dependence of the glass transition temperature of the Ni₆₅Nb₃₅, Ni₆₀Nb₃₅Sn₅, Ni₅₉.₃₅Nb₃₄.₄₅Sn62, Ni₆₀(Nb₄₀Ta₆₀)₃₄Sn₆, and Ni₅₇Fe₃Nb₃₅Sn₅ metallic glass forming alloys was investigated with a differential scanning calorimeter (DSC). The inverse heating rate for each DSC experiment was plotted versus inverse temperature and a Vogel-Fulcher- Tamman (VFT) type relation was...

Creator:: Shah, Minalben B.
Abstract:: 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...

Creator:: Shaw, Tyler A.
Abstract:: 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...
