Bachelors Theses and Reports, 1928 - 1970

The object of this research was to produce a workable electrolytic cell for the continuous deposition of manganese from aqueous sulphate solutions and determine the critical factors in its oper­ation.

The Physiographic History Of Western Montana And Northwestern Idaho, John R. Kavanagh

Bachelors Theses and Reports, 1928 - 1970

Millions of years of physiographic changes have conditioned us to the fact that our present drainage is a temporary feature. Rivers once flowing opposite to their present direction is not an unusual condition for physiographers to suggest.

An Isopach Map And A Discussion Of The Permian In Wyoming And Adjacent Areas, Willard Leskela

Bachelors Theses and Reports, 1928 - 1970

The accelerated post-war demand for petroleum products with resultant high prices and dwindling reserves has spurred producers to an extensive search for new fields and for ad­ditional production in known fields. Exploration and discov­ery is dependent on the collection and correlation of vast amounts of data both in the field and that found in liter­ature.

Roasting And Leaching Of Montana Chromite, Jerry D. Murphy

Bachelors Theses and Reports, 1928 - 1970

The United States, although the leading consumer of chromite, depends almost entirely on imports for its supply. Domestic production of chromite is limited, because high-grade imported ore is plentiful and inexpensive in normal times. There are several large deposits of chromite in the United States, representing millions of tons of low grade ore. These deposits form a strategic reserve that must be used in time of national emergency.

Sulfatizing Roasting Of A Copper Sulfide Ore, Walter D. Finnegan

Bachelors Theses and Reports, 1928 - 1970

At present copper sulfide ores are recovered by pyrometallurgical processes. While the recovery of cop­per from sulfide ores by hydrometallurgical means has long been considered attractive, the impurities, low re­covery and mechanical difficulties have kept this process from becoming commercial.

Geology Of The Lost Creek-Modesty Creek Area Deerlodge County, Montana, Howard B. Nickelson, Robert L. Pott

Bachelors Theses and Reports, 1928 - 1970

In 1915 the United States Geological Survey published a folio by Calkins and Emmons on the geology of the Philipsburg Quadrangle, which ad­joins the area now under study to the west. Geology of this portion of Montana had not been mapped previously; consequently the purpose of this thesis is to make a geological reconnais­sance of the stratigraphy and structure of the area.

A Study Of The Action Of Various Energizers In The Carburization Of Steel, William N. Warren

Bachelors Theses and Reports, 1928 - 1970

The object of casehardening is to produce articles of steel having a tough or ductile interior and a hard sur­face. Quenching produces a surface somewhat harder than the interior, but in order to obtain a high surface hard­ness, the percentage of alloying elements in the steel must be raised to such an extent that the core or central por­tion becomes hard and brittle also.

Geology Of Montana, Stanley G. Olson

Bachelors Theses and Reports, 1928 - 1970

A vast amount of information has been published by many workers on particular features of the geology of the state of Montana, as well as on local geology of many smaller divi­sions. However, a satisfactory summary of the geology in general, which would include all phases of geology as they apply to the greater area of the entire state, has not been published.

A Study Of The Diffusion Of Electroplated Coatings In The Solid State., Michael R. Writt

Bachelors Theses and Reports, 1928 - 1970

The term diffusion means an equalization or homogenization of diverse materials. Specifically ap­plied to metals, diffusion is the interchange of atoms. It is, in effect, an invasion of one crystal lattice by the atoms of one or more other crystal lattices. Therefore, the study of diffusion must involve the geometry and physics of crystal lattices as well as their energies.

Leaching Of Low Grade Rhodochrosite, E. D. King

Bachelors Theses and Reports, 1928 - 1970

Although there are many uses for manganese today, none of them approaches its importance as a deoxidizing agent in the manufac­ture of steels. Without manganese the steelmaking in­dustry would be very seriously handicapped. The metal­lurgy of manganese has been developed around the high-grade ores, and unfortunately, our reserves of high-grade ores are very limited.

The Electrodeposition Of Iron-Manganese Alloys, Kenneth H. Larson

Bachelors Theses and Reports, 1928 - 1970

Although the alteration of properties resulting from the alloying of metals in their usual commercial forms has been extensively investigated, the field of electrodeposition of alloys is believed generally not to have received the atten­tion that it merits.

A Study Of The Physical Properties Of Low Tin Solders, Cornelius P. Dwyer

Bachelors Theses and Reports, 1928 - 1970

In 1947, out of the 100,000 long tons of tin con­sumed in the United States, 25,000 tons went into solder. Tin plate took 39,000 tons while babbit, bronze and coll­apsible tubes accounted for approximately 17,000 tons. Solder ranked second to tin plate and required more than the next three major uses combined.

The Effect Of Manganese And Magnesium On The Hardening Of Copper-Aluminum Alloys, Robert M. Hansen

Bachelors Theses and Reports, 1928 - 1970

During recent years, duralumin and all aluminum alloys have been made the object of much discussion regarding their hardening mechanism. The commercial success of nearly all of the alloys of aluminum and mag­nesium is dependent on their ability to age or precipitation harden.

An Investigation Of Age-Hardening In A Commercial Copper-Beryllium Alloy, Terry Horne

Bachelors Theses and Reports, 1928 - 1970

This investigation is concerned with the age-hardening process as exemplified by the aging of a commercial Cu-Be alloy and, in particular, with this pro­cess as determined by X-ray methods. The amount of infor­mation available on age-hardening of commercial alloys is scanty and what information there is, is inaccurate.

An Investigation Of The Anodic Oxidation Of Aluminum In A Sulfuric Acid Electrolyte, William D. Michaely

Bachelors Theses and Reports, 1928 - 1970

When aluminum is allowed to stand in air or is heated in air, a thin oxide film is produced on the metal. If aluminum is made the anode in a suitable electrolyte and a current applied, a coating is obtained which is similar to that produced in air, but may be effected much quicker. This film is thicker, harder, more resistant to corrosion and abrasion, and more adhesive than the natural oxide. The film is porous and makes an excellent adsorptive for dyes and pigments.

Oxygen Enriched Atmosphere Roasting, Clarence Wells Jr

Bachelors Theses and Reports, 1928 - 1970

The possible benefits of oxygen enriched atmosphere roasting have been known to metallurgists for many years, but only since the development of equipment and processes to produce cheap oxygen in very large amounts has much ser­ious consideration been given this matter.

Geological Studies In Utah, J. Stewart Williams

Faculty Honor Lectures

Utah's thousands of square miles of mountains, plateaus, and i ~ desert basins exhibit a wide variety of geological features and offer the student of geology an endless series of challenging problems. The solution of some of these problems began nearly one hundred years ago with the surveys of the United States territories; the work continues today at a greatly accelerated rate with scores of professional geologists and advanced students in the field each summer. The writer and students under his direction have made some contributions to the solution of a few of these problems in the twelve years that …

A Preliminary Study Of The Benefication Of Montana Kyanite, Donald Paul Mccarthy

Bachelors Theses and Reports, 1928 - 1970

This investigation is a preliminary study of the beneficiation of Montana kyanite, and while preliminary in degree the information gained may serve as a guide for the eventual exploitation of this Montana resource.

Foraminifera From Pleistocene Beds Near San Pedro, California, R. F. Mitchell

Bachelors Theses and Reports, 1928 - 1970

The age of rocks found in drill cores, and consequently the depths to possible oil-bearing formations has in many localities been determined by micro-paleontologic studies during the past three decades. Of the different micro-fossils used in this work, foraminifera have been studied most, are the best described, and hence, by far the most helpful.
