| Abstract Scope |
Shear Assisted Processing and Extrusion (ShAPE) was used to fabricate AA7075 tubing having an outer diameter of 12 mm and wall thickness of 1 mm. Extrusion speeds above 7 meters/min were achieved without surface cracking or tearing, compared to 1-2 meters/min that is typical of conventional extrusion of AA7075. This high rate is enabled by the unique thermomechanical conditions intrinsic to the ShAPE extrusion process. The effects of extrusion speed, die temperature, and post-extrusion heat treatment on mechanical properties will be reported. Results are presented primarily for extrusions made from billets machined out of homogenized castings; however, some data will also be presented for extrusions made from un-homogenized castings. |
