概要

論文の詳細を見る
Recent years, it is known that there are excellent high-temperature properties of YAG matrix composites reinforced with sapphire phase. In this report, we show first successful fabrication of sapphire/YAG eutectic fiber whose diameters are controlled around 200μmφ by micro pulling down (μ-PD) method. Electron diffraction indicates that both sapphire and YAG phases are single crystals with clear boundaries. Tensile test at 1700℃ shows that this fiber has plasticity under such an elevated temperature.
