Research Abstract

This study is aimed to clarify the plastic properties of the ferrite and austenite duplex phase steels at high speed deformation. The stress - strain curves were measured with the sensing block type testing machine at various strain rate ranging from 0.001/s to 1000/s. It was clarified that the duplex phase steel has a significant increase of 0.2% offset stress with the strain rate increasing. The EBSD (Electron back scattering diffraction) measurement was conducted on the samples deformed up to various strain at various strain rate. The misorientation measurement at the vicinity of the phase boundaries were examined and the preferential development of the local misorientation was clarified. This means that the dislocation structure which provides the long range stress field can be easily evolved near the phase boundaries. In addition, the relationship between the dynamic phase transformation and the dislocation structure was also found.
