Rene 80 superalloys have susceptibility to solidification cracking when manufactured with direct energy deposition. This research developed a computational framework for mapping cooling rates, thermal gradients, thermal rates, strain, strain rates, and stress components using thermomechanical simulations, microstructure prediction, and solidification crack susceptibility (by analytical RDG criteria). This work provides a practical physics-based method to evaluate the solidification cracking under a wide range of process conditions validated by experiments.
