Microstructure Studies of Refractory Polycrystalline Oxides

Abstract

The program was concerned with two aspects of this very broad problem; (1) the plastic deformation of fine-grained high purity hot pressed Al2O3 as compared with similarly processed but lower purity material and (2) the stress corrosion of polycrystalline MgO and whether a chemical or mechanical (dislocation) model for failure applies.
