Abstract
In this study, a high-throughput calculation algorithm was compiled for screening the potential alloying elements that can increase the resistance of Al alloy to stress corrosion cracking (SCC). Studies show that the precipitation rate of η/η' phase at the GBs increased by 53 times due to hot rolling. The η/η' phase distribution at GBs decreased the dislocation density by an order of magnitude, which makes the GBs sensitive to SCC. To compensate for these weak sites, the algorithm was utilized to determine the stabilities, diffusion energy barriers, and GB cohesive energy of all elements in the Al.
