Tungsten Base Metal, High Density
1998-09-01
AMST21014
This specification covers the requirements for four classes of machinable, high density tungsten base metal produced by consolidation of metal powder mixtures whose composition is mainly tungsten. This material may be used for uncoated parts or parts that may be coated with other materials for protection against corrosion and abrasion such as, electrodeposited and vacuum deposited cadmium and electrodeposited chromium. Detailed requirements for coatings should be covered in the applicable part drawing, when required.

TUNGSTEN FORGINGS Pressed, Sintered, and Forged
2011-08-15
AMS7897A
This specification covers tungsten in the form of forgings produced from billets processed by isostatically cold pressing, utilizing hydrogen reduced tungsten powder, and high-temperature sintering.
Standard

Forgings, Titanium Alloys Heat-Treated, Finished-Part Properties: Short-Transverse Tensile, Fracture Toughness, and Longitudinal Time-Dependent-Tension

WIP
AMS4938B
This specification establishes requirements for titanium forgings of any shape or form from which finished parts are to be made. (See 8.3, 8.5.4, and 8.7). These forgings are used typically in the manufacture of high-performance parts when control of short-transverse tensile, fracture toughness, tensile creep, or tensile rupture is required, but usage is not limited to such applications.
