| Abstract: | The influence of deformation conditions on softening law of aluminum sheet was studied by multi-pass isothermal compression test.The experimental results show that both flow stress and the softening fraction Fs are influenced by deformation temperature remarkably. Flow stress decreased and the softening fraction increased greatly with the increase of temperature, so the flow true stress-strain curve displayed characteristic of steady-state deformation. |

| Keywords: | aluminum sheet pressure can plastic deformation hot compression flow stress softening |
