reportActive / Technical Report | Accession Number: ADA004998 | Need Help?

Abstract:

In this report, the results of fracture mirror measurements on a wide variety of ceramic materials fractured in flexural tests at various temperatures and in delayed fracture and impact tests at room temperature are presented. Much of this work was done by fractographic observations on alumina, silicon nitride, zircon, steatite, and silicon carbide specimens fractured in an earlier investigation of flaws at fracture origins.
