High Temperature Alloys
Updates to the High Temperature Alloy Data database.
Part of the Advanced Materials – High Temperature Alloys data bundle
- General data updates
-
Statistical information on the test data has been added to the homepage and on individual datasheets as follows:
- New information on the database home page regarding:
- ASTM test standards used for various properties (also quoted on datasheets).
- Notes on interpolation between test temperatures.
- Data clarification – properties are average regression at a given temperature. They are not design minima nor should they be used as such.
- New information on the "Curve information" meta-attribute for individual curves.
- Number of specimens tested per temperature value.
- Curves are typical curves, not design minima.
- New information on the database home page regarding:
- Simulation data updates
-
Simulation-ready data has been added for fatigue S-N curves (for high cycle fatigue) and curve parameters.
S-N curves have been added to 35 records comprising several stainless steels, low alloy steels, Cobalt and Nickel alloys. The Basquin’s Law parameters, Strength coefficient and Strength exponent, as extracted from the S-N curves have also been added to these records.
These can be used for high cycle fatigue simulations requiring S-N curve parameters.
- FEA Exporter updates
-
New exporters have been added to export S-N curves and Paris Law parameters (for fatigue crack growth rate) directly to Ansys Workbench, as follows:
- Two exporters are provided for S-N curves: one for temperature-dependent S-N curves, and the other for R-ratio dependent S-N curves.
- Exporter for fatigue crack growth rate now exports Paris Law parameters, in all Workbench units.
