| Outline of Final Research Achievements |
The purpose of this research is the development and feasibility study of solder welding of graphite based materials with the use of carbide fluxes. As the first step, the boron carbide was selected for the flux. Due to the spot heating with a high power laser, the molten state of the flux was achieved and lamellar structure of eutectic alloys was observed. The glassy carbon was expected for the use of lightweight structural materials. The welding test of glassy carbon and boron carbide was successfully performed.
