| research | data | how to reach us | in the news | pointers | from the MSEL Annual Report 1997:Technology Transfer Standard Reference DatabasesMSEL developed 8 databases that contain information about materials properties. Seven of these databases are available through the NIST Standard Reference Data Program. A list of databases currently available through this venue and a brief summary of their contents are provided below. A polymer composite database was recently completed and will be available during FY98. More detailed information about the content of these databases and how to acquire them is provided through the at the following e-mail address: http://www.nist.gov/srd/srd.htm#nsrds.htm.
Designed for phase characterization obtained by electron diffraction methods, this database and associated software permit highly selective identification procedures for microscopic and macroscopic crystalline materials.
The database of materials properties provides evaluated property data for high temperature superconductors. The range of materials covers the many series of compounds derived from the Y-Ba-Cu-O, Bi-Sr-Ca-Cu-O, Tl-Sr-Ca-Cu-O and La-Cu-O chemical families, along with numerous other variants of the cuprate and bismuthate, and borocarbide materials that are known to have superconducting phases.
The software permits searches for diagrams by chemical system, author, or year of publication. The database includes all diagrams from Volumes 1-10, annual volumes for 1991-93, and Phase Equilibria Diagrams (PED) for High-Tc Superconductors in the PED series.
Version 2.0 contains thermal, mechanical, and corrosion properties of silicon carbides and silicon nitrides in a self-contained database system that operates on DOS-based personal computers. This database contains state-of-the-art materials property data for both research and commercial grades of silicon carbides and silicon nitrides.
Corrosion databases and expert systems developed under the NACE-NIST Corrosion Data Program give users reference data for general guidance on the performance of engineering materials in corrosive environments. ˇ COR×SURŽ 1 includes data for 25 common metals for exposures in over 1,000 corrosive environments at various temperatures and concentrations. ˇ COR×SURŽ 2 provides similar data for 36 nonmetallic materials (elastomers, polymers, composites, thermoplastics, etc.) in over 850 environments.
NIST Crystal Data contains chemical, physical, and crystallographic information useful to characterize more than 210,403 inorganic and organic crystalline materials. The data include the standard cell parameters, cell volume, space group number and symbol, the calculated density, and classification by chemical type, chemical formula, and chemical name. Each entry has an associated literature reference. |
