The Influence of Grain Boundaries on Creep of KBr
Most creep experiments on alkali halides have used single crystal specimens, and only relatively little information is available on the creep characteristics of polycrystalline materials (primarily LiF and NaCl). In addition, there is the possibility of marked differences in impurity content between the single and polycrystalline samples, which make it difficult to compare the limited data at present available. Accordingly, this paper describes a series of experiments conducted on KBr with the objective of overcoming these difficulties.
