Study of the Relative Localized Corrosion and Cracking Susceptibility of Additively Manufactured and Wrought Corrosion Resistant Alloys
Abstract
Funds are provided to quantitatively define the relative susceptibility of AM materials vs. conventional processing in key corrosion modes such as crevice corrosion, intergranular corrosion, and environmental cracking; to identify controlling microstructural feature(s) and link to processing such as powder, AM parameters, post-build treatment; to define fundamental damage mechanisms linking composition/microstructure/processing with corrosion performance; and to define mitigation strategies to improve resistance to corrosion modes based on the study. The outcome of the study can provide valuable information to the improved design of AM processes that maintain mechanical properties while improving corrosion properties, and AM alloys that take advantage of the abilities of AM, including compositionally-graded structures.
