Significantly improved weldability in laser welding of additively manufactured haynes 230 superalloys by tailoring microstructure

Owing to restrictions on forming dimensions, laser powder bed fusion (LPBF) components will continue to require laser welding in the future. The post-weld thermal cracking of LPBF-Haynes 230 superalloys has become a key issue hindering their assembly in service. In this study, it was found that both...
