Unveiling the effect of stress on vacancy diffusion isotropy at high temperature in Ni-Re Systems: Insights from atomic simulations

Stress-affected vacancy diffusion significantly impacts the element distributions in Ni-based single-crystal (SX) superalloys, determining their precipitate coarsening and creep behaviors under service conditions consequently. Rhenium (Re), as a slow-diffusing element, exhibits nonnegligible effects...
