Abstract: Provided are an information processing method and apparatus, a device, and a storage medium. The information processing method includes: receiving target information, a session identifier of a source session group, and indication information that are transmitted by a server, in which the target information is generated based on to-be-forwarded information from the source session group, and the indication information indicates a type of the source session group; determining a display range of the target information and operation permission of the target information based on the indication information and the session identifier of the source session group; and rendering and displaying the target information in a target session based on the display range of the target information and the operation permission of the target information.

Abstract: 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.
