Tom J, Look here about Ampliforge


Maybe you missed this post. It would be easy to miss. I should have used a more descriptive header.

RE:Hmmm....Alcoa process...Ampliforge.

Take a look at everything, especially the patent referenced. Give us your takeaway.



BTW, AMPLIFORGE may be an acronym - sort of, maybe.

Additive Manufacturing Process (LI?) FORGE - maybe a play on the word (and meaning) AMPLIFY.



Also and separately, from the referenced patent:

[0032] The final forged product may be used in the aerospace, aviation, or medical industries, for example. The final forged product could be, for example, a turbine or blade. In one embodiment, the final forged product is a blade for a jet engine.

[0033] As mentioned above, after the additive manufacturing step (100), the metal shaped -preform may be forged (200) to create a final forged product. In other embodiments, after the additive manufacturing step (100), the metal shaped-preform may be processed via other forms of working (e.g., hot working) to create a final worked product. For instance, the working of the metal shaped-preform may also or alternatively include rolling, ring rolling, ring forging, shaped rolling, and/or extruding to create the final worked product. In some embodiments, the final worked product may realize improved properties, such as improved porosity (e.g., less porosity), improved surface roughness (e.g., less surface roughness, i.e., a smoother surface), and/or better mechanical properties (e.g., improved surface hardness), among others, in some embodiments, the final worked product may realize a predetermined shape. In some embodiments, the metal shaped-preform may be ring rolled, ring forged and/or extruded (e.g., forced through a die) to create a hollow final worked product. In some embodiments, the metal shaped-preform may be rolled to produce a final worked product that realizes improved porosity. In some embodiments, the metal shaped-preform may be shape rolled to produce a final worked product that realizes a predetermined shape (e.g.. a curve having a specified radius).
