Revisiting the influence of Cr and Ti on the γ'-Ni₃Al phase dissolution and precipitation kinetics: A combined study using diffusion couples, CALPHAD, and DFT
Key Points
Dissolution and precipitation kinetics of the gamma-prime phase are influenced by chromium and titanium content, suggesting compositional significance.
Key evidence shows Ti addition leads to enhanced stability, significantly impacting dissolution rates in specific nickel aluminum alloys.
Analysis using diffusion couples and CALPHAD data provided insights into phase behavior under varying temperature and composition conditions.
Findings support the need for tailored alloy compositions to optimize performance in high-temperature applications.
