The Construction And Operation Of A Universal Specimen Mount With Protective Lead Shield For The Purpose Of Determining Pole Figures Using The Schulz-Decker Transmission Technique, Richard L. Fausner Jun 1953

The Construction And Operation Of A Universal Specimen Mount With Protective Lead Shield For The Purpose Of Determining Pole Figures Using The Schulz-Decker Transmission Technique, Richard L. Fausner

Bachelors Theses and Reports, 1928 - 1970

It was the purpose of this study to construct a universal mount, to construct a protective lead shield, to operate the instrument, and to provide a pole figure using the transmission method of Schulz and Decker. There are at present several lengthy x-ray methods of determining the grain orientation of metals. These methods are mainly photographic. In order to provide a rapid means of obtaining the necessary information concerning the grain orientation of a metal, a universal mount was constructed.


The Effect Of Germanium On The Current Efficiency In The Electrolysis Of Pure Zinc Sulfate Solution, Keith R. Bock May 1953

The Effect Of Germanium On The Current Efficiency In The Electrolysis Of Pure Zinc Sulfate Solution, Keith R. Bock

Bachelors Theses and Reports, 1928 - 1970

It has long been recognized that electrolytic zinc cells are extremely sensitive to impurities. In fact, cer­tain impurities present in amounts as low as 0.1 mg/1 cause a serious loss of current efficiency. Also, the presence of several impurities in the electrolyte may accelerate the detrimental effect of each impurity.


Recrystallization Of High Purity Aluminum, Virgil H. Griswold Jr. May 1953

Recrystallization Of High Purity Aluminum, Virgil H. Griswold Jr.

Bachelors Theses and Reports, 1928 - 1970

If a metal is first cold-worked and then heated to a sufficient temperature for an adequate length of time, the hardening properties due to cold-working disappear, and the metal will return more or less to its original state. Upon examination of the microstructure, we find that new grains have replaced the old grains through what is called recrystallization. The final size of the recrystallized grains depends upon three important variables--the degree of cold-work or deforma­tion, annealing temperature, and annealing time.


The Effect Of Manganese On The Age Hardening Of Aluminum-Copper Alloys, Keith P. Burgess May 1953

The Effect Of Manganese On The Age Hardening Of Aluminum-Copper Alloys, Keith P. Burgess

Bachelors Theses and Reports, 1928 - 1970

It is known that age-hardening occurs in alloys of the solid solution type containing a hardening constituent, of a metal or metallic compound which is more soluble in the solvent phase at higher tempertures than at lower temperatures.
