| Abstract: | The mechanic behavior of TC4 alloy during hot compressiong deformation is studied with isothermal compression test.It is manifested that the flow stress and structure of TC4 alloy are dominated mainly by the deformation temperature nd strain rate.A flow stress epuation is obtained through regression anlysis,which can be used to determain the thermal deformation processes of TC4 alloy. |

| Keywords: | TC4 alloy Hot compression Flow-stress Deformation temperature strain rate |
