Microstructure and corrosion behaviour of wire arc additive manufactured AA2024 alloy thin wall structure
نویسندگان
چکیده
In the present work, microstructure and corrosion behaviour of wire arc additive manufactured (WAAM) AA2024 alloy thin wall structure are investigated. Three distinctive zones in WAAM structure, including melt pool zone (MPZ), border (MPB) heat affected (HAZ). Localized initiates at multi-phase lamellar eutectic via de-alloying S-phase (Al2CuMg) intermetallics. MPB is most susceptible to localized due its relatively high volume fraction resulted from alloying elements segregation during solidification.
