| Abstract: | The flow stress behavior of the LY12 aluminum-alloy during plastic deformation at elevated temperature was studied by isothermal compression test using Gleeble-1500. The results show that the flow stress is controlled by both strain rate and temperature. The effects of the deformed temperature, train rate and deformed degree to flow stress were analyzed. |

| Keywords: | aluminum-alloy hot compression flow stress strain rate |
