GRAIN-BOUNDARY SLIDING IN NON-METALLIC BICRYSTALS. Final Report

Technical Report ·
OSTI ID:4782829
Lack of agreement between experimental investigations concerning the creep properties of non-metallic crystalline solids raises doubts as to whether high-temperature polycrystalline anelasticity effects can always be unequivocally related to grain-boundary sliding, and to doubts as to whether grain-boundary sliding actually occurs in nonmetals. An investigation of grain-boundary sliding by studying directly the grain-boundary behavior in deformed bi-crystals of selected non-metals is described. Specime s studied included alumina, magnesia, and NaCl. It wa that NaCl and magnesia exhiblt grain-boundary sliding effects. It is noted that the experiments were not extensive enough to test the general theory of grain-boundary sliding; however, the observations are in general agreement with those of other investigators.
