Two dimensional numerical simulation of a non-isothermal GaAs MESFET

Creator:: Lin, Angela A.
Abstract:: The low thermal conductivity of gallium arsenide compared to silicon results in self-heating effects in GaAs MESFETs that limit the electrical performance of such devices for high power applications. To date, analytical thermal models of self heating in GaAs MESFETs are based on the assumption of a uniformly heated channel....

Thermodynamics of the Pd₄₃Ni₁₀Cu₂₇P₂₀ metallic glass-forming alloy

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....

On the fragility and equilibrium phases of metallic glass forming alloys

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...

Thermodynamis and kinetics of Zr₅₈̣₅Cu₁₅̣₆Ni₁₂̣₈Al₁₀̣₃Nb₂̣₈ bulk metallic glass forming alloy

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...

Surface temperature effects on the fouling characteristics of cooling water

Creator:: Story, Michael Kenneth
Abstract:: A cooling tower system was built and fouling resistances were studied for cooling water flowing over a heated tubular surface. The cooling water studied was formulated in an effort to match industrial cooling water quality. The water used in this study had an average Ryznar Stability Index of 6.23 and...

Temperature profiles of spheres packed in regular arrays

Creator:: Cunningham, Mitchel Eugene
Abstract:: An analytical solution is developed for the temperature profile of a unit cell consisting of a sphere of one material centered in a cube of a second material. All material properties are considered constant and boundary conditions consist of specified temperatures on the top and bottom faces of the cube...

Thermal stability of surface treated zirconium

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...
