Abstract

See full text

A deformation-driven solid-phase extrusion device and a one-step alloy bar preparation method by using the same are provided. The device includes a stir tool, an extrusion container and an ejector rod. The stir tool has an integral structure composed of an upper mounting part and a lower working part and having a hollow channel. The lower working part is disposed in a groove of the extrusion container, and the ejector rod is disposed in the hollow channel of the stir tool. The method includes adding alloy powder to the extrusion container, enabling the stir tool to exert a pressure and revolve at a high speed to cause large plastic deformation of the powder and generate heat by friction and deform among powder and the friction working surface of the working part, sintering the alloy powder and extruding the same through the hollow channel of the stir tool.
