Selection & Design Role
Carbide, boride and nitride systems for extreme heat flux, oxidation-managed hot structures and leading edges. Selection must remain tied to exact material identity, architecture, process state and service environment.

WEB-MAT Revision 1.0 · Phase 20 release candidate
Primary Engineering Context
qualitative architecture; numerical claims remain source-gated
Processing & Integration
Manufacturing route, constituent condition, interfaces, joining or consolidation state, defects and quality controls remain part of the engineering record.
Environment & Degradation
Temperature, chemistry, radiation, vacuum, moisture, cyclic loading, aging and other relevant degradation drivers are tracked as configuration-dependent conditions.
Verification & Qualification
Property values require units, specimen/process condition, test method, source provenance, evidence level, maturity and application-specific acceptance criteria.
Controlled Engineering Record
| Control area | Required content |
|---|---|
| Material identity | Exact composition, grade, constituent architecture, product form and supplier designation where applicable. |
| Process / condition | Manufacturing route, heat treatment or cure, consolidation, surface state, porosity/defect state and relevant history. |
| Performance fields | Only source-supported property values with units, temperature/environment and test basis; no rendering-derived design data. |
| Failure / degradation | Relevant fracture, fatigue, creep, wear, oxidation, corrosion, aging, interface or environment-driven mechanisms. |
| Evidence / availability | E0–E5 evidence grade and A0–A5 availability state retained with source provenance and maturity controls. |
