| Outline of Final Research Achievements |
In order to clarify the origin of the deformability of the brittle cementite phase in the pearlite microstructure, consisting of the cementite and ferrite phases, we have investigated the physical and mechanical properties of single crystals of the cementite phase in a confined volume, with the aid of microscale fabrication and testing techniques. We have elucidated that many slip systems are operative in the cementite phase even at room temperature via single-crystal micropillar compression. We have successfully determined some of the single-crystal elastic constants via inelastic X-ray scattering.
