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
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
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.
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
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.
The Metallography Of Aluminum Casting Alloys, Donald D. Goehler
The Metallography Of Aluminum Casting Alloys, Donald D. Goehler
Bachelors Theses and Reports, 1928 - 1970
The purpose of this thesis is to supply the Montana School of Mines with an up to date source of information concerning the metallography of aluminum casting alloys. This thesis is designed as a continuing project. Ultimately, it is hoped that a catalog containing all the typical structures of aluminum casting alloys will develop.
The Age-Hardening Of Aluminum With Mgzn2, Sidney E. Worthen
The Age-Hardening Of Aluminum With Mgzn2, Sidney E. Worthen
Bachelors Theses and Reports, 1928 - 1970
The purpose of this thesis is to investigate the age-hardening of aluminum with magnesium and zinc in such proportions as to conform to the compound MgZn2.
Because of a lack of time and proper equipment, the only property investigated was the hardness as indicated by the Rockwell Superficial Hardness Tester.
The Age Hardening Of Silver With Copper-Silicide, Joseph Edward Shaw
The Age Hardening Of Silver With Copper-Silicide, Joseph Edward Shaw
Bachelors Theses and Reports, 1928 - 1970
The successful application of the phenomenon of precipitation hardening to aluminum and copper has indicated the possibility of hardening all metals in the same way. The phenomenon of age hardening was discoveredin 1911, and since that time much research has been carried on in all parts of the world on various alloy systems.
Structure Of Eutectics, Dilip K. Das
Structure Of Eutectics, Dilip K. Das
Bachelors Theses and Reports, 1928 - 1970
The present paper is a result of work done on the study of structures of eutectics of a certain eutectic-forming binary systems. In this research work no systems with intermetallic compounds have been studied.
The Electroplating Of Cadmium From Sulfate Solutions, Lewis S. Prater
The Electroplating Of Cadmium From Sulfate Solutions, Lewis S. Prater
Bachelors Theses and Reports, 1928 - 1970
It has been proven that cadmium forms a very satisfactory plate on steel, which has to withstand severe corrosion, especially the corrosion of sea water and spray. The metal is now successfully plated electrolytically from cyanide solutions, but wherever work is carried on with cyanide, there is great danger of poisoning to the workers.
The Electrolytic Deposition Of Chromium Upon Aluminum, E. Fults, L. D. Voerge
The Electrolytic Deposition Of Chromium Upon Aluminum, E. Fults, L. D. Voerge
Bachelors Theses and Reports, 1928 - 1970
The purpose or this investigation is primarily to determine the best conditions for plating chromium on aluminum. The work was carried out with the hope of obtaining coherent deposits, and of determining the conditions under which such deposits may be duplicated.
