Technical Reference Publication

Excerpt
Introduction: This report describes the major technical activities and accomplishments of the Metallurgy Division of the NIST Materials Science and Engineering Laboratory (MSEL) in 1998. The NIST Metallurgy Division mission is to provide critical leadership in developing measurement methods, standards, and fundamental understanding of materials behavior needed by US industry for the more effective production and use of both traditional and emerging materials. As part of this mission we are responsible not only for developing new measurement methodologies with broad applicability across materials classes and industries, but also for working with individual industry groups to develop and integrate measurements, standards, and evaluated data for specific, technologically important applications.
