| Outline of Final Research Achievements |
We have recently found a possibility to endow a new class of ultra-high temperature structural materials with high strength and high toughness simultaneously by utilizing interphase boundaries in directionally solidified in-situ eutectic composites. In the present study, we have systematically investigated microstructure - mechanical property relationship in various transition-metal silicide based eutectic composites in order to verify the strategy and to clarify the requirement for applying the strategy. In addition, deformation behaviors of various transition-metal silicides have been investigated by mechanical tests of micrometer-sized single crystals to
elucidate the deformation mechanism of the component phases in the eutectic composites.
