| Abstract Scope |
Ferritic/Martensitic steels are favored for their strength, high temperature performance and weight reduction potential in structural applications. Conventional weldments require post weld heat treatments (PWHT) to restore material performance; alternative solid-state or adhesive joining methods can limit design flexibility. The primary objective of this work is to demonstrate a proof-of-concept for an integrated welding and thermal processing joining method to improve the ductility and toughness of as-welded joints without subjecting the assembly to a separate energy intensive PWHT, which is associated with risks of distortion and cracking. The improvements in properties afforded by such a method can greatly expand the design opportunities for high performance structural components. |
