SYSTEM AND PROCESS FOR FORMATION OF EXTRUSION STRUCTURES |
| 摘要 |
An extrusion apparatus and process are disclosed that produce high-performance extrusion structures. The extrusion apparatus includes a shear tool that applies a rotational shear force and an axial extrusion force to the face of a billet material that plasticizes the billet material. Plasticized material is extruded through an extrusion die along the length of the inner bore of the shear tool which yields hollow and solid extrusion structures. The process refines the microstructures of the extrusion structures and extrusion materials. |

1. A shear-assisted extrusion system for production of an extrusion structure, the system comprises:
a shear tool configured to simultaneously apply a rotational shearing force and an axial extrusion force to the face of a billet material at the shear tool/billet interface that plastically deforms the billet material, the shear tool includes an extrusion die with an orifice having a selected shape that extrudes the plasticized billet material that forms the extrusion structure with a selected shape at an axial extrusion force less than that required for extrusions performed absent the rotational shearing force. |
