Copper Converter: Basic Research Testing With A Plastic Model Converter And Four Types Of Refractories, Arthur C. Bigley Jr.
Copper Converter: Basic Research Testing With A Plastic Model Converter And Four Types Of Refractories, Arthur C. Bigley Jr.
Bachelors Theses and Reports, 1928 - 1970
In recent years there has appeared an increasing number of papers on converting operations as related to thermodynamics. This approach is a powerful, potential tool. However, the development of new ideas and changes must rely on accurate basic information.
Microradiography Of Metals And Alloys Using A Medical X-Ray Unit, W. R. Byrne
Microradiography Of Metals And Alloys Using A Medical X-Ray Unit, W. R. Byrne
Bachelors Theses and Reports, 1928 - 1970
There is no doubt that the microradiograph technique is of value to the metallurgist. A three-dimensional picture to supplement the photomicrographs should give a true picture of the microstructure. Microradiography can be used where etchants can not differentiate between the various components or where no etchant can be found suitable for a particular alloy.
Secondary Recrystallization In Copper, James E. Thompson
Secondary Recrystallization In Copper, James E. Thompson
Bachelors Theses and Reports, 1928 - 1970
The purpose of this thesis is to study the conditions under which secondary recrystallization will take place in copper. The variables considered were the time annealing, the temperature of annealing, and the degree of cold work undergone by the specimen before it was subjected to the heat treatment.
Comminution Studies, George A. Grandy
Comminution Studies, George A. Grandy
Bachelors Theses and Reports, 1928 - 1970
Comminution, reduction in size, is one of the most important, yet least understood, steps in mineral dressing. So that more efficient comminuting devices may be designed and constructed, a better knowledge of the relationship between energy consumption and size reduction is desired. Occasional studies during the last 100 years have produced a few "laws" purporting to describe this relationship. In each case, the promulgators and supporters of these laws have presented experimental evidence for their verification. Obviously, all of these advocated practices cannot be correct. To the mill designer, the problem is "Which, if any, of these laws are valid." …
Growth Of A Preferentially Oriented Aluminum Single Crystal, John George Bjeletich
Growth Of A Preferentially Oriented Aluminum Single Crystal, John George Bjeletich
Bachelors Theses and Reports, 1928 - 1970
When studying some anisotropic property of a specific metal, such as the critical shear stress of aluminum, it is desirable that the test specimen be a single crystal with the crystal axes preferentially oriented. Therefore, it is necessary to obtain a single crystal by one of the methods mentioned and by use of x-rays to determine the orientation. Once the single crystal is obtained and the orientation known, it is possible to grow a preferentially oriented aluminum single crystal by a method generally known as "seeding". The purpose of this thesis problem was to grow a crystal by utilizing the …
The Identification Of Montana Clays By X-Ray Analysis, James Francis Donovan
The Identification Of Montana Clays By X-Ray Analysis, James Francis Donovan
Bachelors Theses and Reports, 1928 - 1970
This investigation is concerned primarily with the determination of the various clay minerals comprising certain deposits through the state. This investigation was accomplished with the use of X-Ray diffraction equipment and it can be easily understood why this equipment has been of such benefit to the clay mineralogist.
The Macromosaic Structure Of Lead Single Crystals, Eldon J. Nicholson
The Macromosaic Structure Of Lead Single Crystals, Eldon J. Nicholson
Bachelors Theses and Reports, 1928 - 1970
The purpose of this investigation is to examine this structure [macromosaic] to determine any properties or characteristics peculiar to it that could shed light on its cause or on the basic mechanism of crystal growth from the melt.
Autoclave Leaching Of Montana Chromite, Leonard S. Greely
Autoclave Leaching Of Montana Chromite, Leonard S. Greely
Bachelors Theses and Reports, 1928 - 1970
The purpose of this investigation was to determine the feasibility of caustic autoclaving of Montana chromite in order to recover the chromium in a relatively pure solution of sodium chromate.
