| Outline of Final Research Achievements |
TEM in-situ straining measurements for Fe base alloys revealed that dislocations disappear at the grain boundary during deformation, which is not consistent with conventional of pile-up model. In the case of a steel containing carbon with fine microstructures, strain burst is retard due to a high resistance to dislocation motion. The fine structure causes low dislocation mobility and depresses a dislocation multiplication leading to a planar dislocation structure. The size of plastic zone underneath the indenter induced by ex-situ indentation is smaller for Fe-Si alloy that that of IF steel.
