26 Metals and Metallic Materials

Includes physical, chemical, and mechanical properties of metals and metallic materials; and metallurgy.


Metallic Materials – Materials that are like metal; having the properties of metal; containing or consisting of metal.

NASA Interest

Exhaustive Interest : Physical, chemical, and mechanical properties; testing, evaluation, and protection of metals, alloys, and related compositions for use in aircraft, rockets, launch vehicles, space vehicles, reentry vehicles, aircraft and spacecraft propulsion systems, and supporting facilities (other than conventional building structural materials).

Selective Interest : Research and development on metallic materials that have potential aerospace applications.

Negative Interest : Routine developments of structural metallic materials for use in housing, heavy industry, and earthbound transportation, unless a potential exists for aerospace use.
