AMS 4994 - 6Al-4V Titanium Alloy Hot Isostatic Pressed (HIP) Compacts
AMS 4994 is the specification for 6Al-4V Titanium Alloy hot isostatic pressed (HIP) compacts produced by powder metallurgy. Hot isostatic pressing applies simultaneous high temperature and isostatic pressure, typically 15,000 psi at 900°C, to densify powder compacts to near-100% theoretical density, producing mechanical properties that approach or match wrought 6Al-4V titanium.
HIP compacts per AMS 4994 combine the geometric freedom of near-net-shape powder processing with the mechanical properties required for fracture-critical aerospace applications. They are used for complex structural fittings, valve bodies, manifolds, and turbine engine components where wrought material cannot economically achieve the required geometry and porosity-free HIP properties are mandatory.
6Al-4V is recommended for use at temperatures from -350° to 750°F (-210° to 400°C). Applications outside this temperature range are possible in certain situations. The alloy is weldable. Complex shapes can be made via hot forming. It machines like an austenitic stainless steel.
