With the increasing prevalence of polymer composites in engineering applications, invariably mechanical failures of these components are occurring. Key to addressing this is fractographic analysis; the examination of fracture surfaces to deduce information about the damage and failure of components. The fractography of isotropic materials, particularly metals, has been used as a tool for many y...
the fracture resistance of all-ceramic restorations is one of the major concerns in clinical applications of these materials. before initiating a time-consuming and costly clinical investigation, an in vitro study can help to estimate the in vivo usability of a new dental material. mechanical properties of all-ceramic materials are frequently evaluated to predict their clinical performance. sin...
In this study, the correlation existing among grinding, surface integrity, and flexural strength is investigated for WC-Co cemented carbides (hardmetals). A fine-grained WC-13 wt % Co grade and three different surface conditions: (1) ground, (2) mirror-like polished (reference), and (3) ground plus high-temperature annealed, are investigated. Surface integrity and mechanical characterization is...
