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 Indium-Mercury Constitutional Diagram, Bert E. Lake
The Indium-Mercury Constitutional Diagram, Bert E. Lake
Bachelors Theses and Reports, 1928 - 1970
Whenever metals differ greatly in electropositivity, intermetallic compounds are likely to form in preference to solid solutions. 21ercury and indium show a considerable difference in electropositivity. This would indicate that intermetallic compounds may play an important role in the constitutional diagram for the mercury-indium system.

Oil Shales In Montana, Richard N. Miller
Oil Shales In Montana, Richard N. Miller
Bachelors Theses and Reports, 1928 - 1970
Montana has long been known to have very large resources of coal and oil, and undetermined amounts of oil shale. The reserves of coal and oil have been proven, in part, and have been produced commercially, but not much is known about the extent and apparent value of the oil shales. Under present .conditions, and according to standards set by the United States Bureau of Mines, the shales are not of commercial value. They are, however, a potentially valuable mineral resource, and portions of them will possibly be utilized, although not in the near future.
