Crack mitigating and microstructure engineering through in-process mechanical work in wire directed energy deposited Invar alloy

Abstract Wire-based directed energy deposition (WDED) of Invar alloys is prone to cracking due to high thermal stresses and microstructural anisotropy. In this study, in-process machine hammer peening (MHP) was integrated into WDED to mitigate cracking and control the microstruct...
