Microstructural evolution and mechanical behavior of 800H alloy for control rods in HTGRs under long-term thermal exposure

The 800H alloy, a candidate material for control rods in High-temperature gas-cooled reactors, requires exceptional mechanical stability under prolonged service (650 °C) and transient accident conditions (900 °C). However, systematic studies on its long-term thermal exposure behavior remain limited....
