Dye Impregnation Method for Revealing Machining Crack Geometry

April 1, 2000
Author(s)
Yasumitsu Matsuo, M. Sando, L K. Ives, Ryna B. Marinenko, George D. Quinn
An observation technique for machining cracks in ceramics has been developed. Palladium (Pd) nitrate water solution was impregnated into a bending specimen using cold isostatic pressing. Following a failure test, crack geometry was determined from a Pd

VARMAS After Twelve

July 1, 1999
Author(s)
George D. Quinn
The Versailles Advanced Materials and Standards VAMAS project is a forum for prestandardization research. It has helped spread awareness of new testing and characterization methods around the world. Technical Working Area (TWA) 3-Ceramics has been active

Standard Reference Material 2100: Ceramic Fracture Toughness

June 30, 1999
Author(s)
George D. Quinn, R J. Gettings, K Xu
A new Standard Reference Material (SRM) has been prepared for ceramic fracture toughness. It is the first reference material in the world for the property fracture toughness for any class material (metal, ceramic, polymer). The SRM may be used with any

VAMAS Technical Working Area #3

March 1, 1999
Author(s)
George D. Quinn, E F. Begley
Technical Working Area #3, Ceramics of the Versailles Advanced Materials and Standards (VAMAS) project has conducted 12 projects and 12,000 experiments over 12 years. This website explains TWA3, and lists the key accomplishments and publications from the

Hardness Testing of Ceramics

August 1, 1998
Author(s)
George D. Quinn
An overview of hardness testing of ceramics is presented. Conventional test methods are discussed, particularly with respect to major sources of experimental error and standardization. Two NIST Standard Reference Materials (SRMs) are highlighted. Emerging

Characterization of Fracture Origins in Advanced Ceramic Materials

May 1, 1998
Author(s)
George D. Quinn, J Swab, E F. Begley
This NIST web site will complement ASTM standard C1322-96, Standard Practice for Fractography and Characterization of Fracture Origins in Advanced Ceramics. The objectives of the web site are to prove a thumbnail sketch of the standard, promote its usage
