| Description: | Technical Report Abstract: A commercial deep-freeze unit was modified to serve as a laboratory for growing single crystals, cutting specimens of a given orientation, testing these specimens in compressive creep, and studying thin-sections of the results on a universal stage. A method of growing single crystals of adequate size was developed by adapting the Bridgman method. Forty-one creep tests were made at temperatures ranging from -1° to -18°C. These gave an unexpected form of creep-curve in which the rate of strain continuously increases with time. The mechanism of deformation is dominantly basal translation - consistent with earlier work. The dependence on temperature and stress is expressed empirically. |
