Growth Of A Preferentially Oriented Aluminum Single Crystal, John George Bjeletich

Bachelors Theses and Reports, 1928 - 1970

When studying some anisotropic property of a specific metal, such as the critical shear stress of aluminum, it is desirable that the test specimen be a single crystal with the crystal axes preferentially oriented. Therefore, it is necessary to obtain a single crystal by one of the methods mentioned and by use of x-rays to determine the orientation. Once the single crystal is obtained and the orientation known, it is possible to grow a preferentially oriented aluminum single crystal by a method generally known as "seeding". The purpose of this thesis problem was to grow a crystal by utilizing the …
