Multi-Constraint Screening-Guided IN718 Addition for Crack Suppression and Improved Mechanical Properties of Laser-Directed Energy-Deposited IN738LC

IN738LC is a γ′-strengthened superalloy for hot-section components up to 900 °C, but its high Al + Ti content makes it susceptible to cracking during laser-directed energy deposition (LDED). Adding IN718 suppresses cracking but degrades the intrinsic γ′ fraction and the calculate...
