Stress-Corrosion Cracking Of Brass, Paul A. Fossey
Stress-Corrosion Cracking Of Brass, Paul A. Fossey
Bachelors Theses and Reports, 1928 - 1970
the mechanism of stress-corrosion cracking of brass has been sought for many years. Investigators have proposed many mechanisms, but each of these mechanisms has always had several drawbacks. This paper presents an account of experimental work done in the laboratory on this subject and compares it to the work of previous investigations. It evaluates the mechanisms presented by investigators and shows the failures of these mechanisms. A theory of Nitrogen Embrittlement is presented and an evaluation of this theory with experimental work follows.

Bachelors Theses and Reports, 1928 - 1970
In the past few years a great deal of attention has been given to the electrodeposition of alloys. For the main part, this investigation has been of scientific interest only; but in a few instances, such work has attained commercial importance.

The reclamation of metals from scrap is becoming increasingly important in the metallurgical industry. Copper, because it does not corrode readily and is electronegative to most common metals, is peculiarly adapted to reclamation.

Electrolytic Recovery Of Copper And Zinc From Brass, D. H. Swank
Bachelors Theses and Reports, 1928 - 1970
The purpose of this research was to continue the work of Thomas Parker, who worked on the recovery of copper and zinc from brass during the school year l934 - 1935. Since there is such a wide variety of brasses made with usually a third alloying constituent, remelted scrap is suitable only for castings of wide tolerance in specifications.

Reclaimed metals, or secondary metals, are becoming of great importance in the metal industries of the world. Secondary metals are an important factor in production. The increase in the secondary production of copper is due to many factors. One of these may be its permenance, that is, the metal does not corrode very readily. Another reason for increase in production is the high price paid for it.
Effect Of Impurities Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solution, Robert Jess Smith
Effect Of Impurities Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solution, Robert Jess Smith
Bachelors Theses and Reports, 1928 - 1970
There are many elements which are detrimental to the current efficiency in the electrolysis of zinc sulphate solution. Fortunately the majority of these elements are easily removed in the purification process and cause no further trouble. The elements that are likely to cause trouble in ordinary plant operations are antimony, arsenic, cobalt, nickel, manganese and germanium. The following tests were made to determine the mutual effect on the current efficiency when several of the impurities were present in the electrolyte.
