This study addresses the challenge of optimizing creep resistance in wrought superalloys, particularly focusing on how small variations in titanium (Ti) and aluminum (Al) content influence precipitation kinetics of c¢ and r-phase. Wrought CrCoNi-base C-264 superalloy is explored, exhibiting a relatively low c¢-phase volume percentage of 12.5 pct, making it susceptible to deformation yet suitable for high-temperature applications in aviation and power generation. The methodology involves systematic investigations utilizing experimental and simulation approaches to understand the effects of Ti and Al variations on phase stability, microstructure, and creep properties between 880°C and 1000°C. The results indicate that small compositional changes can significantly affect the precipitation behavior and subsequent mechanical properties of these alloys, highlighting the complexities associated with multicomponent superalloys. These findings contribute to optimizing the material's performance under increased operational demands, thereby advancing the applicability of wrought superalloys in extreme environments.
