Polymorphic Transformations of Partly Stabilized ZrO2 at Broken Specimen Surfaces of Transformation-Strengthened Ceramic as a Result of Different Force and Thermal Action

Results are provided for a study of high-density ceramic based on partly stabilized ZrO2 with a Y2O3 content of about 2.0 mol.%. Strength properties, structure, and phase composition are specified at the original basal surfaces and failure surfaces for ceramic specimens with force mechanical action, and also under low-temperature conditions (liquid nitrogen or helium). Results obtained are compared with known published data.
