Prismatic Slip of A1 2 O 3 Single Crystals Below 1000°C in Compression Under Hydrostatic Pressure

Alumina single crystals were compressed perpendicular to the [0001] axis at a constant strain rate between 20° and 950°C. At r>200°C, failure was suppressed by_hydrostatic pressures of 500 to 1500 MPa. Prismatic slip {1120}〈1100〉 was deduced from optical observations of the lateral surfaces and from... View More
