Specific grain-boundary fracture energy

The fracture energy value that often features in theoretical discussions on ceramic strength for normal polycrystalline material is the specific fracture energy of the grain boundaries y . Unfortunately, y is hard to measure directly and so almost no experimental data exist. It is common to see y approximated to lattice fracture energy y as a fraction ranging... [Pg.106]

Thus, from a knowledge of the average lattice stress intensity factor for the material and a measurement of PIF from an SEM micrograph, K c be found. The specific fracture energy of the grain boundary is then given as... [Pg.107]
