Development of Environment‐Time‐Dependent Material Selection Maps for Alloy 718 Under Crevice Conditions in Aerated Seawater

open access: yesMaterials and Corrosion, EarlyView.
This study introduces material selection maps—that is, charts indicating crevice corrosion resistance as a function of temperature and electrochemical potential—illustrating their applicability using nickel‐based alloy 718 as a case study. Crevice corrosion susceptibility maps developed in this study are a new approach that shows how environmental ...
