Improving tensile property and creep resistance of a high γ′ phase polycrystalline superalloy via adjusting grain boundary

Key Points

• Enhanced tensile properties observed, leading to improved performance in high-stress environments.
• Creep resistance increased by optimizing grain boundary characteristics in the superalloy structure.
• Study employs mechanical testing to evaluate tensile and creep behaviors across various grain boundary configurations.
• Findings suggest that fine-tuning grain boundaries can positively impact the superalloy's durability and application in high-temperature settings.
