Effect of Co/Ni ratio on precipitation phase evolution and element distribution behavior in as-cast Co-Ni-based superalloy

Key Points

• The Co/Ni ratio influences the precipitation phase evolution in Co-Ni-based superalloys, affecting their properties significantly.
• Key evidence indicates that changes in the Co/Ni ratio alter elemental distribution behaviors within the alloy's microstructure.
• This analysis investigates the impact of varying the Co/Ni ratio in as-cast Co-Ni-based superalloys across multiple compositions.
• Insights from this study may enable improved design and performance of superalloys in high-temperature applications.
