STUDIES OF THE BRITTLE BEHAVIOR OF CERAMIC MATERIALS.

Abstract

This report rep9esents a joint effort of investigators on the broad subject of fundamental factors affecting the brittle behavior and strength of ceramic oxides. The materials used in this investigation were in single crystal as well as polycrystalline forms of MgO and Al2O3. The work on individual studies includes: (Task 2)-Strain Rate Effects, (Task 5)-Internal Friction and Creep in Polycrystalline Al2O3, (Task 6)-Effect of Surface Energy, (Task 7)-Fracture Mechanisms, (Task 8)-Effect of Impurities on the Properties of Ceramics, (Task 10)-Effects of Thermal-Mechanical History on the Mechanical Properties of Ceramics, (Task 6)-Effects of Polyaxial Stresses, (Task 20)-Influence of Surface Conditions on Strength of Oxides, (Task 2)-Residual Stresses in Oxide Ceramics, (Task 22)-Strength-grain Size-Porosity Relations in Al2O3, and (Task 23)Hot Extrusion.
