| Outline of Final Research Achievements |
The structure and properties of carbon-steel is strongly dependent on the amount of carbon as well as the form of carbon. When the carbon-steel is aged at low temperatures, the carbon clusters are usually formed and result in the increase strength of the carbon-steel. In this research, a TEM holder was developed for in-situ heating analysis for the aim of understanding the strengthening mechanism of carbon-steel with carbon clusters, and the generation/dispersion state and crystal structure of carbon clusters were examined. In addition, in-situ tensile experiment was carried out to observe the interaction between carbon clusters and dislocations.
