摘要： Disclosed herein is a method for improving the formability of an aluminum alloy sheet by locally modifying the surface of the aluminum alloy sheet. The method comprises: a sheet fixing step of fixing a sheet to be locally surface-modified; and a local surface modification step comprising adhering a probe closely to a region of the fixed sheet, which is in need of surface modification, by the application of pressure, and then rotationally moving the probe on the region at high speed. According to the method, the region of the sheet in which a fracture can occur due to the concentration of strains and stresses during the formation of the aluminum alloy sheet into a product is subjected to local surface modification so as to improve the formability of the aluminum alloy sheet compared to the parent metal, so that the aluminum alloy sheet can be easily formed into a product. If necessary, the friction coefficient of the probe can be changed by forming various shapes of fine embossments or fine protrusions on the lower surface of the probe, which comes into contact with the sheet, so that plastic flow can be changed to adjust the depth of the plastic region of the sheet, thus further improving the formability of the sheet.

摘要： A communication terminal includes a controller to, when a call set up between the communication terminal and a second communication terminal in an internet protocol network is released, encapsulate in a call release request message call status information relating to at least one status of the call and transmit the call release request message. The communication terminal further includes an output element coupled to the controller to transmit the call release request message. The call release request message includes the call status information and information indicating the call release.
