摘要: The hardness of hot-pressed silicon nitride ceramics has been measured over a wide range applied loads, 0.02 to 300 N, for both Vickers and Knoop indenter geometries. indentation size effect (ISE) was evident loads less than about 1 N. values agree provided they are compared at given penetration the respective indenter. influence residual stresses ceramic surface on response in as-machined, polished, post-annealed state investigated. results discussed relation characterization damage brittle materials fracture analysis models.
