Access to decades of metals research from
Japan's National Institute for Materials Science

This data module provides searchable access to metals property data from Japan’s National Institute for Materials Science (NIMS), experts on the long-term behavior of metallic materials. The creep and fatigue characterization data generated by NIMS is important for design, maintenance, and overhaul of, for example, power stations and processing plants. This world-leading data-set results from years of continuous testing of metals including carbon steels, low alloy steels, high chromium steels, and austenitic stainless steels, as well as iron-based, nickel-based, and cobalt-based alloys.

For the first time, users are able to access and use the underlying raw numerical data as opposed to simply viewing published graphs and figures. The data is available through the leading materials information management system, GRANTA MI™, which gives easy web browser-based access and allows users to search, plot, and export data for use in Computer Aided Engineering (CAE). Installing GRANTA MI on a corporate network can also provide fast, integrated, enterprise-wide access to in-house and other reference data, complementing the NIMS dataset.

Dr. Toshio Ogata, Station Director of the Materials Information Station at NIMS, said, "We are delighted that the valuable creep and fatigue data, resulting from many years of research at NIMS, is now more widely accessible. This will help engineers to create safe, secure, and sustainable products and structures."

A fatigue datasheet for a Carburizing Steel (0.20C-1Cr, FDS037, JIS SCr4O2). The graph of rotating bending fatigue has been filtered to show only those materials polished with a cloth, but with different hardenings. The resulting chart can be copied to the clipboard, or the raw data itself can be exported.

The data module makes it possible to

  • Access raw NIMS materials data via the simple browser-based user interface of GRANTA MI, making it easy to search and view.
  • Access (including print and save) both PDF copies of the original NIMS publications and a 'live' database providing the raw property data for search, comparison, analysis, and export to CAE/CAD. (For example, the figure above shows how you can filter to a specific surface finish: the resulting chart can be copied to the clipboard, or the raw data itself can be exported.)
  • Link directly from items of data to the relevant PDF pages, providing full traceability back to the source document for all information. Footnotes in the original PDF documents are referenced and reproduced within the datasheets (as in the Creep Datasheet example below)

A selection of the data available for creep rupture stress vs time to rupture, at a range of elevated temperatures, for a low alloy steel. The footnotes from the original publication are linked through to the data (and reproduced in the datasheet), maintaining full traceability to the detailed research.

What is in it?

Creep Datasheets—59 datasheets covering over 40 materials (steels, superalloys, and 1 cobalt alloy)  in pipe, tube, and plate form. It provides room temperature and elevated temperature (650C) elastic data (modulus, strength, reduction in area, elongation) as well as creep rupture data. In some materials, data is available up to 400,000 hours.

Fatigue Datasheets—115 datasheets covering 51 materials (mainly steels) at both elevated and room temperature. It provides elastic, high cycle fatigue, low cycle fatigue, time dependent low cycle fatigue (at elevated temperatures), as well as high cycle fatigue and crack propagation data on welded joins and material in the heat affected zone.


Advantages of the Granta module

Advantages of accessing this data via the GRANTA MI system include:

  • Data can be rapidly searched, manipulated, and applied in analysis and design
  • Property-based search—i.e., locate materials that have desired properties (or combinations of properties) rather than simply look up properties for a known material
  • Materials comparison—compare materials quickly and easily, select the most suitable for your application
  • Export data directly to computer aided engineering and design packages—including Abaqus, ANSYS Workbench, CATIA, Pro/ENGINEER, and Creo Elements/Pro format
  • Ensure that all of your engineers see the same, up-to-date, version of the data
