The purpose of this investigation was to design and construct a laboratory size electrolytic cell in which to reduce alumina, using the same basic materials that are used in a commercial size cell. The cell was designed to have a capacity of approximately 100 grams of metallic aluminum produced every 8 hours. The cell was constructed so it could be operated continuously.
Design And Calibration Of A Ferromagnetic Torsion Balance, Oliver W. Moen
Design And Calibration Of A Ferromagnetic Torsion Balance, Oliver W. Moen
Bachelors Theses and Reports, 1928 - 1970
Magnetic materials can be divided into three major groups; diamagnetic, paramagnetic and ferromagnetic. From a magnetic point of view, the ferromagnetic are the most interesting. Ferromagnetic materials include the elements iron, nickel, cobalt, certain of the alloys of these elements and a group of alloys first studied by Huesler. These latter are ferromagnetic largely because of the presence of manganese in special combination with the other non-ferrous elements.

Geology Of The Ragged Point Oil Field Musselshell County, Montana, David M. Amos
Geology Of The Ragged Point Oil Field Musselshell County, Montana, David M. Amos
Bachelors Theses and Reports, 1928 - 1970
The Ragged Point oil field is located in Northwest Musselshell County, in the Lake Basin field of central Montana, and on the western border of the Great Plains region. The surface topography is that of a plain marked by erosion and moderate folding. The stratigraphy of central Montana shows periodic marine invasions from the Cordilleran trough, with normal marine limestones interbedded with sandstone sand shales. These sediments are over 12,000 feet thick, with the Cretaceous Eagle and Colorado formations exposed at the surface on the Ragged Point anticline. Undifferentiated Cambrian limestones and shales are the oldest rocks encountered in drilling.
Beneficiation Of Scheelite Ore From The Potosi Tungsten Mining District, James A. Ndulue
Beneficiation Of Scheelite Ore From The Potosi Tungsten Mining District, James A. Ndulue
Bachelors Theses and Reports, 1928 - 1970
The now increasing importance of tungsten as a metal with desirable properties in high strength and high temperature resisting alloy steels, coupled with the recent discoveries of low-grade tungsten ore deposits in Montana, has spurred a search for suitable and economical methods of treating tungsten ores of the State. This search has been conducted on a variety of tungsten ores and the present work is rather an aspect of the whole tungsten beneficiation problem in Montana.
Effect Of Carbon Content In Steels Upon The Deposition Of Titanium From A Fused Salt Bath, Reinhard Paul Abendroth
Effect Of Carbon Content In Steels Upon The Deposition Of Titanium From A Fused Salt Bath, Reinhard Paul Abendroth
Masters Theses
"STATEMENT OF PROBLEM Previous work done at the Missouri School of Mines and Metallurgy on the deposition of titanium upon various metals, especially iron and steel, bas shown that titanium can be deposited upon ingot iron and. low carbon steels with comparitive ease. Difficulty was encountered in attempts to deposit titanium upon steels of higher carbon content and upon cast irons.
For this reason, it was decided to investigate more thoroughly the relationship between the carbon content of various steels and the quality of titanium coatings deposited on these steels. Once this relationship had been established, a suitable theoretical explanation …
A Study Of The Deformation Texture And Its Variation In Cold Drawn Nickel Rods, Krishan Kumar Tangri
A Study Of The Deformation Texture And Its Variation In Cold Drawn Nickel Rods, Krishan Kumar Tangri
Doctoral Dissertations
"The production of rods by cold drawing is a development of recent years as compared to other methods of fabrication. Though a good many investigations correlating the observed mechanical properties to the mill practices employed have been reported, the results nevertheless are more of a qualitative and empirical nature. It is well known that the physical properties of a metal product are related to its deformation textures which are characteristic of the metal and the fabricating method used. Thus a study of the deformation textures of cold-drawn rods, specially by x-ray diffraction techniques should provide a much more precise and …
The Rate Of Dissolution Of Aluminum In Hydrofluoric Acid, Yen-Ngen Wang
The Rate Of Dissolution Of Aluminum In Hydrofluoric Acid, Yen-Ngen Wang
Doctoral Dissertations
"Pure aluminum has a relatively low strength, and its use is, therefore, rather limited. However, the resistance of pure aluminum to the attack of acids and many neutral solutions is higher than that of less pure aluminum or most of the aluminum-base alloys. For this reason, alclad alloy sheets, are made with a coating of pure aluminum on one or both sides of an aluminum alloy core. The coating is metallurgically bonded to the core over the entire area of contact. Thus the coating electrochemically protects the core from corrosive attack.
Aluminum is more negative in the electrochemical series than …
Mechanism And Measurement Of First Stage Graphitization In White Cast Iron, David S. Gould
Mechanism And Measurement Of First Stage Graphitization In White Cast Iron, David S. Gould
Masters Theses
"The original object of this thesis was to ascertain if coercive force measurements could be used for the determination of degree of malleablization in malleable iron. Since first stage graphitization was involved, it was only natural that an interest in the mechanism of first stage graphitization developed. The investigation which resulted from this interest was done primarily for the edification of the author, however it was subsequently deemed of enough importance to be included in this thesis. For this reason the thesis may appear at times to deviate from the original objective"--Preface, page iii.
Hydrogen Overvoltage On Titanium, Sheng-Tai Shih
Hydrogen Overvoltage On Titanium, Sheng-Tai Shih
Doctoral Dissertations
"The hydrogen overvoltage has been defined as the difference between the potential of the working electrode (cathode) and the theoretical reversible value for the same solution. This definition brings out the difficulty involved in the measurement of the "theoretical reversible potential for the same solution” as the potential of the hydrogen electrode in such a solution is usually different from the value of a standard reversible hydrogen electrode, for which the activity of hydrogen ions is set as being “1” and the potential arbitrarily set as being “0”. Besides, it is sometimes necessary to add addition agents to the solution …
Deposition Of Metallic Coatings From Fused Salt Baths, Andrew Hessler Larson
Deposition Of Metallic Coatings From Fused Salt Baths, Andrew Hessler Larson
Masters Theses
"This thesis is the result of an investigation undertaken to study some of the important factors affecting the deposition of metallic diffusion coatings on other metals immersed in a fused salt bath….
There are many methods which have been devised to obtain diffusion coatings on various metals. One which is quite well known and used commercially is the process of “chromizing” which produces a diffusion layer if chromium on another metal. One method of “chromizing” consists of immersing the specimen to be coated in a mixed chloride fused bath containing chromium metal flakes. Another method consists of packing a low …
Corrosion Products Of Titanium In Fused Salt Baths, Kai-Chai Chiou
Corrosion Products Of Titanium In Fused Salt Baths, Kai-Chai Chiou
Masters Theses
"Titanium is gaining great interest in the modern metal industry because of its natural abundance and its desirable physical and chemical properties. Among them, its excellent corrosion resistance, such as the resistance to normal atmosphere attack, humid and saline atmosphere attack, sea water attack, and nitric acid attack, is the most prominent characteristic being welcomed by the engineers. The usefulness of titanium would be greatly increased if it were possible to plate titanium on other metals, thus increasing the corrosion resistance of these other metals.
Much concern, at present, has been given to the possibilities of the electrodeposition of titanium …
