The Transformation Of The Aluminum-Zinc Eutectoid Alloy At Subcritical Temperatures, Thomas Joseph Burke
The Transformation Of The Aluminum-Zinc Eutectoid Alloy At Subcritical Temperatures, Thomas Joseph Burke
Masters Theses
"Interest in the mechanism of the austenite eutectoid transformation in iron-carbon alloys, especially as produced by the isothermal sub-critical techniques introduced by Davenport and Bain, has resulted in the application of similar heat treatment studies to the eutectoid transformations in other alloy systems. The study of the eutectoid transformation is of both fundamental and industrial interest because past experience has shown that these studies yielded much information concerning the nature and mechanism of the changes in eutectoid alloys during the decomposition of the phase stable at high temperatures and has also contributed much toward the development of new properties to …
The Potassium Tungsten Bronzes, Ching Hou Ma
The Potassium Tungsten Bronzes, Ching Hou Ma
Masters Theses
"The tungsten bronzes are a series of substitutional solid solutions of alkali or alkaline earth metatungstates and tungstic oxides. They are not really metallic alloys or intermetallic compounds but they possess some marked metallic properties such as metallic luster, good electric conductivity, high specific gravity, etc. For this reason the name of "bronzes" is applied to them"--Introduction, page 1.
The Nature Of Molecular Films Of Oleic Acid On Quartz, Kenneth Lee Keating
The Nature Of Molecular Films Of Oleic Acid On Quartz, Kenneth Lee Keating
Masters Theses
"The purpose of this research was to show the nature of oleic acid on quartz mineral by transferring calcium oleate films, known to be monomolecular and of a definite orientation, to the surface of a piece of quartz, and measuring the resulting coated mineral by contact angle technique"--Introduction, page 1.
A High-Temperature X-Ray Diffraction Camera And Its Application To Copper And Titanium, Robert R. Penman
A High-Temperature X-Ray Diffraction Camera And Its Application To Copper And Titanium, Robert R. Penman
Masters Theses
"The purpose of this research was threefold, and consists of the following sections: 1. Effective use of a high temperature x-ray camera, capable of reaching temperatures of 1000 ºC. 2. Investigation of the thermal dilation of certain cubic metals. 3. Accurate determination of the lattice constant (aₒ) of Beta Titanium at 900 ºC "--Introduction, page 1.
Solid Solution In The Series Sodium Tungsten Bronze, Lithium Tungsten Bronze And Tungstic Oxide, Godrej F. Doctor
Solid Solution In The Series Sodium Tungsten Bronze, Lithium Tungsten Bronze And Tungstic Oxide, Godrej F. Doctor
Masters Theses
"The tungsten bronzes are a series of anionic substitutional solid solutions of alkali metal metatungstates and tungstic oxide. They are neither alloys nor intermetallic compounds, the term tungsten bronzes was adopted because of their remarkable metallic properties, e.g. luster, specific gravity and especially high electrical conductivity, which resembles to that of graphite. Due to its chemical inactivity and beautiful shades of color, it is used as a coating, especially in the plastic industry and for other ornamental products. The properties and the structure of these bronzes have not been investigated entirely satisfactory; within the last twenty years, only a few …
Separation Of Cobalt From Zinc Sulfate Solutions By Synthetic Cation Exchange Resins, Wen-Hsiang Chang
Separation Of Cobalt From Zinc Sulfate Solutions By Synthetic Cation Exchange Resins, Wen-Hsiang Chang
Masters Theses
"The purpose of the present research is primarily to investigate the possibility of the separation and recovery of cobalt from zinc sulfate solutions by means of cation exchange resins. It is thought that such an investigation, seemingly of academic interest, might throw some light on determining the possibility of processing some industrial solutions containing both cobalt and zinc. Cobalt, for instance, has been well known as one of the most detrimental impurities in zinc electrolytic solutions. In spite of various purification treatments, small amounts of cobalt are often present in the electrolytic solution, causing a reduction in current efficiency and …
Construction And Operation Of A Vacuum Retort Pilot-Plant For Distillation Of Alloys, Robert Frederick Doelling
Construction And Operation Of A Vacuum Retort Pilot-Plant For Distillation Of Alloys, Robert Frederick Doelling
Masters Theses
"The widespread appearance of large scale vacuum systems operating commercially in the micron range of pressures has initiated a new field of industrial endeavor, vacuum engineering. The ever increasing number of applications of vacuo in commercial processes and laboratory research has stimulated the design and improvement of vacuum equipment, and at the present time equipment may be obtained to meet practically any need. In turn, the variety of available tools has directed the engineers attention to improving old processes and developing new ones through the utilization of vacuum techniques ... The possibility of producing a relatively high purity silver in …
A Study Of Cast Eutectic Structures By Means Of Optical And X-Ray Microscopy, John Stanton Winston
A Study Of Cast Eutectic Structures By Means Of Optical And X-Ray Microscopy, John Stanton Winston
Masters Theses
"The present research is the result of interest in two rather broad, and at first thought, seemingly entirely separate topics: the structure of eutectics and x-ray microscopy. D. Hanson in 1923 in his correspondence with Albert M. Portevin in regard to his article on the structure of eutectics states, "A point that always stuck him (D. Hanson) in examining eutectics was that one of the constituents always formed a continuous phase round the other one. The orientation of one constituent was either constant or varied in a uniform manner. What, however, was the condition of the 'enveloped' constituent, which formed …
Separation Of Copper And Zinc On Synthetic Resins, Ernest Joseph Breton
Separation Of Copper And Zinc On Synthetic Resins, Ernest Joseph Breton
Masters Theses
"It was desired to know whether ion exchange resins could be of value to the metallurgist in the recovery and separation of metals. The recovery and separation of copper and zinc from dilute solutions on Amberlite IRC-50, a carboxylic resin, and Amberlite IR-120, a nuclear sulfonic resin, were investigated. It was found that Amberlite IRC-50 could effectively remove copper ions from a solution of copper and zinc. Amberlite IR-120, due to the strong sulfonic acid groups, exhibited only a slight preference for copper as compared to zinc. It would seem that a judicious choice of resins coupled with appropriate chemistry …
