High-Temperature Material Data Best Practices
Best practices for obtaining and managing high-temperature material data for creep analysis — data sources, quality, coverage and traceability.
Key practices
- Obtain creep data from qualified sources (material databases, test programmes, published data)
- Ensure the data covers the operating temperature and stress range
- Verify the material condition (alloy, heat treatment, product form) matches the component
- Check the data quality: test method, specimen count, scatter
- Do not extrapolate creep data beyond 1.5x the test duration without justification
- Document the data source, material specification and data quality assessment
