Design And Preliminary Testing Of A Thermomechanical Rock Fragmentation Apparatus, Gary Earl Fenton

Masters Theses

"The design characteristics of equipment to thermally weaken and mechanically fragment hard rock were developed and the apparatus constructed. An initial investigation of thermo-mechanical fragmentation was conducted on Missouri red granite. The particles from the fragmentation tests were sized and this analysis was used in the Rittinger theory to calculate surface area breakage energy. It was found that the application of thermal energy could reduce the surface area breakage energy per unit volume of material removed by as much as 41 percent. The use of kerfs in the rock increased the amount of material removed and permitted larger particles to …

A Study Of The Dislocation Instability And Reverse Martensitic Transformation In Fe-Ni System, Chung Lim

Masters Theses

"Since the martensitic reaction is a strain transformation, the transformation of the lattice structure can be induced by an external stresses. This also means that the macroscopic total elastic constant should decrease as the temperature is lowered to M_s on cooling. For the reverse transformation an anomalous decrease of the elastic constant is to be expected as the temperature increases to A_s on heating. In this experiment measurements of the velocity change of an ultrasonic wave in Fe-Ni alloys were carried out for the reverse martensitic transformation. The deviation from the linear relationship of the velocity change as …

The Pm3m-Fm3m Transformation And Phase Equilibrium In Solid Solutions Of Csc1 With Kc1, Rbc1, And Csbr, John David Weyand

Masters Theses

"Thermal expansion and the Pm3m t Fm3m transition of cesium chloride have been studied with high temperature diffractometry, differential thermal analysis, and heating and quenching techniques. The onset temperature of the transition in pure CsCl, on heating, is 471ºC. There are no observable premonitory effects below the transition temperature and no apparent structural relationships between the polymorphs is apparent. Both phases coexist over a 20º to 50ºC temperature range and equilibrium thermal hysteresis occurs on heating and cooling. Hysteresis behavior is explained by addition of strain energy parameters to the free energy function. Initiation of the Pm3m t Fm3m transformation …

A Comparative Study Of Experimental And Computed Compressibility Factors Of Methane - Nitrogen - Helium System, Promod Kumar Taneja

Masters Theses

"The volumetric data for methane, nitrogen, and helium mixtures have been determined experimentally at low temperatures (60ºF to -30ºF) over a pressure range of 1000 to 5000 psig. An attempt has been made to show that the extension of standard techniques viz, "The Law of Corresponding States" for predicting the compressibility factors of pure hydrocarbons and hydrocarbon mixtures is not adequate for mixtures containing even very small amounts of helium. The deviation from the computed compressibility factors is found to be maximum at low temperatures and high pressures (up to 22%) for the mixtures studied"--Abstract, page ii.

Evaluation Of A Cation Isotopic Substitution Technique In Conjunction With A High Temperature Gas Pycnometer For Determining The Stoichiometry Of Materials, Michael Clair Graves

Masters Theses

"This study was concerned with the evaluation of a high temperature gas pycnometer, used in conjunction with a cation isotopic substitution technique, for determining the stoichiometry of materials. Three methods were investigated for determining the correction factors for the thermal gradient effects in the gas pycnometer. The correction factors were shown to be dependent on the temperature, the sample volume, and the height of the sample in the sample chamber. Under the conditions of these experiments, the correction factors were shown to be essentially independent of sample grain size and pycnometer atmosphere. The determination of the stoichiometry of cadmium oxide …
