a Comparison of RF models trained by the pure experimental corrosion dataset or ab-initio calculation modified dataset. b Three different Al alloys, AA5083, AA6N01, and AA7N01, were placed in Southeast Asia (Singapore, Jakarta, and Bangkok) for 2 years to examine the generalization ability of the RF model with phase calculation. c Corrosion morphology and statistics on the number and depth of pits in Al alloys after field exposure.
