Methods of Producing Wrought Products with Internal Passages |
| 摘要 |
Various methods are disclosed for additively manufacturing a feedstock material to create an AM preform, wherein the AM preform is configured with a body having an internal passage defined therein, wherein the internal passage further includes at least one of a void and a channel; inserting a filler material into the internal passage of the AM preform; closing the AM preform with an enclosure component such that the filler material is retained within the internal passage of the AM preform; and deforming the AM preform to a sufficient amount to create a product having an internal passage therein, wherein the product is configured with wrought properties for that material via the deforming step. |
