GRAIN BOUNDARIES AND THE MECHANICAL BEHAVIOR OF MAGNESIUM OXIDE,

Abstract

The paper compares the mechanical behavior of magnesium oxide single crystals and polycrystals at different temperatures. Single crystals show increasing interpenetratability and multiplicity of slip systems at elevated temperatures. Above 1700C slip is very flexible, i.e., slip systems with different Burgers vectors completely interpenetrate each other and slip occurs over a variety of slip planes. Furthermore, above 1600C rearrangement of dislocations by polygonization is observed and in certain cases recrystallization can be obtained.
