Creator:: Kuno, Masahiro
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:: Hayes, Troy A.
Abstract:: Zirconium press plates have been developed for the production of melamine coated particle board, using shot-peening to achieve the desired plate (and therefore coated particle board) surface texture. Service temperatures of the press plates approach 200°C. This study examined the microstructural effects of extended exposure of shot-peened zirconium to temperatures...

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...

Creator:: Bothara, Manish G.
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...

Creator:: Karapetrova, Euguenia
Abstract:: In order to achieve a better understanding of the processes that occur during formation and sintering of zirconia, various chemical and physical techniques were used. Along with Perturbation Angular Correlation spectroscopy, that allowed us to investigate microscopic properties inside the nanometer-size zirconia grains, such techniques as Scanning Electron Microscopy and...

Creator:: Garfinkel, David
Abstract:: Duplex stainless steels (DSS) are an attractive potential material in nuclear power generation systems due to an excellent combination of corrosion resistance, strength, toughness, and affordability. Thermal embrittlement caused by phase instability in the temperature range of ~300-550°C severely limits the service temperature of DSS. The rate of embrittlement varies...
