Selection & Design Role
Material and surface systems for oxidizing, saline, acidic, alkaline, hydrogen and chemically aggressive service. 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. |
