| Research Abstract |
Warm temperature uniaxial tension test was conducted for high strength steel sheet. The decrease of flow stresses were found as the increase of temperature and the decrease of strain rate. V and U shape bending tests were conducted at warm temperature. From the forming tests, it was found that warm forming is effective for the reduction of springback deformation. Additionally, relaxation during holding in the die is very effective to reduce springback. Finally, cyclic bending experiment was proposed to observe Bauschinger effect at warm temperature. It was found that the Bauschinger effect appeared even at the warm temperature.
