Fractography of Advanced Structural Ceramics: Results from the VAMAS Round Robin Exercise.

Abstract

Fractography of ceramic specimens and components is critical to the design and future use of ceramic materials in commercial applications. In 1992 the U.S. Department of Defense released Military Handbook 790 'Fractography and Characterization of Fracture Origins in Advanced Structural Ceramics' which furnished guidelines for the comprehensive interpretation of ceramic fractographic information. Even with the release of this handbook there were still some issues which warranted further study. A round robin exercise sponsored by the Versailles Project on Advanced Materials and Standards (VAMAS) was conducted to determine the applicability of the handbook and to attempt to clarify any ambiguous sections or issues. The exercise was divided into three topics. Topic #1 addressed the detection and interpretation of machining damage on photographs of ceramic specimens. Topic #2 dealt with the fractographic analysis of ceramic specimens. Topic #3 was optional, and asked the participants to perform fractography on a ceramic material of their choice. (MM)
