Tailoring secondary grains via recrystallization control to restore creep life in high-oxygen PM superalloys

Key Points

• Restored creep life indicates improved durability and performance of high-oxygen superalloys, particularly under stress.
• Key evidence demonstrates a significant increase in creep resistance of treated materials by up to 30% under high-temperature conditions.
• Observational analysis focused on recrystallization control, examining its effects on grain structure and overall material integrity.
• This study suggests that tailored recrystallization techniques may lead to advancements in material design for high-stress applications.
