Degradation mechanisms and microstructural evolution of ZrB2-doped SiC fibers in high-temperature steam environments

Key Points

• ZrB2-doped SiC fibers experience notable microstructural changes under high-temperature steam environments, leading to degradation mechanisms.
• Key findings indicate that exposure to steam significantly alters the fiber's microstructure, affecting performance and lifespan.
• Assessment using thermal analysis and microscopy methods demonstrates the critical effects of high-temperature environments on these materials.
• Understanding these degradation mechanisms may enable the development of more durable fiber materials for extreme conditions.
