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
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
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
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
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.

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

Geology And Mines Of The Upper Blackfoot Valley, Montana, Thomas K. Shea
Geology And Mines Of The Upper Blackfoot Valley, Montana, Thomas K. Shea
Bachelors Theses and Reports, 1928 - 1970
The purchase and continued operation of the Mike Horse mine in the Heddleston district, by the American Smelting and Refining Company, gives the Blackfoot Valley a renewed promise of a prosperous future in its role as a mining district. In the past, large amounts of placer gold were recovered from the gulches of the area, however, because of the transportation facilities, only the upper portions of a few lodes were exploited by the early miners.
Rugose Corals Of The Madison Group, William R. Paine
Rugose Corals Of The Madison Group, William R. Paine
Bachelors Theses and Reports, 1928 - 1970
One of the best types of index fossils, and one which occurs most plentifully in the Madison group of formations in Montana, and yet, one which has been little studied, is the group of rugose, or cup, corals. Perhaps this group of fossils has not been studied in detail because their distinguishing characteristics are mainly internal, and laboratory preparation in the form of thin section or polished surfaces is necessary to bring out these characteristics.
Kibbey Sandstone In Montana, Glen Shean
Kibbey Sandstone In Montana, Glen Shean
Bachelors Theses and Reports, 1928 - 1970
Much attention has recently been given, by geologists, to prolific water bearing horizon and a potential oil horizon, known as the Kibbey sandstone, which lies deeply buried under much of central Montana. In some localities the sandstone is dry, and its identification in cuttings from deep wells has in many cases proved difficult.

An Investigation Of A Particular Weldment Failure, Byron Clow
Bachelors Theses and Reports, 1928 - 1970
Two sets of weld-test coupons, supposedly made under identical conditions, were submitted to this institution last year for approval and certification under the A.S.M.E. Welder's Qualification Code. The first set of coupons was unsatisfactory. The second set, made by the same operators one month later, was satisfactory.
Corrosion Testing Of Iron-Tin Alloys By The Salt Spray Method, Bernard T. Mcdonald
Corrosion Testing Of Iron-Tin Alloys By The Salt Spray Method, Bernard T. Mcdonald
Bachelors Theses and Reports, 1928 - 1970
The purpose of this study was to determine the relative rate of corrosion of iron-tin alloys containing low percentages of tin. Since in the world today, a great deal of work is being done to develop large tin deposits and new methods devised to treat these ores, it is possible that the metal will become abundant and will obtain a more important position in the metal industry.
The Corrosion Resistance Of Iron-Tin Compacts As Produced By Powder Metallurgy, Robert W. Gambill
The Corrosion Resistance Of Iron-Tin Compacts As Produced By Powder Metallurgy, Robert W. Gambill
Bachelors Theses and Reports, 1928 - 1970
The art of Powder Metallurgy deals with the preparation of metal powders and their utilization. As a more pertinent definition, the following has been suggested: "Powder Metallurgy is the art of producing metal powders and shaped objects from individual, mixed, or alloyed metal powders, with or without the inclusion of non-metallic constituents".
Geology And Mineral Deposits Of Idaho: A Summary, Paul B. Bronken
Geology And Mineral Deposits Of Idaho: A Summary, Paul B. Bronken
Bachelors Theses and Reports, 1928 - 1970
The great diversity on mineral wealth in Idaho establishes it as one of the principle mining states in the union. Mining first began in the state with the discovery of placer gold in the Pierce City district in 1861, and since that date has become one of the leading industries of the state.
Upper Cretaceous Sediment In Montana, Frank J. Frankovich
Upper Cretaceous Sediment In Montana, Frank J. Frankovich
Bachelors Theses and Reports, 1928 - 1970
Cretaceous sediments in Montana record events during a period of unusual geologic interest. After a long period of extensive submergence of the area during Jurassic time, came a period of varying continental and marine deposition with consequent variations in the types of sediments laid down. A study of these variations, their extent, and their cause has been the primary object of this thesis.
The Problem Of The Tensleep Sandstone, George D. Mccarthy
The Problem Of The Tensleep Sandstone, George D. Mccarthy
Bachelors Theses and Reports, 1928 - 1970
Sandstone is probably one of the most important groups of rocks in existence today. The economic importance of so insignificant a thing as a mass of sand grains grows with the true reality of the situation. By increasing our knowledge of grains of sand, or particles of sandstone in all their ramifications, it would undoubtedly reflect upon our everyday life by increasing commercial possibilities of an undeveloped natural resource of Montana.
Isopach Maps And Discussion Of The Ordovician And Devonian Of Montana And Adjacent Areas, Arden F. Blair
Isopach Maps And Discussion Of The Ordovician And Devonian Of Montana And Adjacent Areas, Arden F. Blair
Bachelors Theses and Reports, 1928 - 1970
The intensive postwar search for new petroleum horizons has resulted in widespread prospecting in the northern Great Plains. No commercial production has as yet been derived from Ordovician or Devonian rocks in Montana, but the relatively few tests that have penetrated to critical depths have disclosed encouraging conditions which merit further consideration, especially in Devonian strata.
Occurrence Of Native Copper Near Jefferson City, Montana, Terence G. Kirkland
Occurrence Of Native Copper Near Jefferson City, Montana, Terence G. Kirkland
Bachelors Theses and Reports, 1928 - 1970
Sometime prior to 1870, a group of prospectors made what was believed to be a "rich strike' on one of the tributaries of Prickly Pear Creek in Jefferson County, Montana. Instead of striking it rich, they had uncovered a native copper deposit, worthless to them because of its limited extent and remote location, but now of much interest to the geologist, and to the mining engineer because of its possible commercial value.
Electro-Deposition Of Iron From A Chloride Bath, Charles W. Noon
Electro-Deposition Of Iron From A Chloride Bath, Charles W. Noon
Bachelors Theses and Reports, 1928 - 1970
Iron was electro-deposited from a ferrous chloride bath. Studies were made of deposits formed when current density was varied, and finally when both current density and temperature were changed. An attempt was made to lay the ground work for a long range study of the chloride bath, and to determine the most simple conditions possible for obtaining a smooth, even, and thick deposit.
General Geology And Mines Of Northwestern Montana, Robert L. Sandvig
General Geology And Mines Of Northwestern Montana, Robert L. Sandvig
