Persistent lattice strain mismatch controls high-temperature strength degradation in 3YSZ

Key Points

• High-temperature strength degradation is closely linked to persistent lattice strain mismatch during material use.
• Data indicates that degradation rates can reach significant levels when strain mismatch is prevalent in 3YSZ ceramics.
• Analysis of material properties through thermal and mechanical testing identifies strain mismatch as a critical factor.
• Understanding this relationship may lead to improved materials that can withstand higher temperatures effectively.
