Metal additive manufacturing (AM) for structural components is limited by low durability properties (toughness, fatigue strength) from microscale porosity inherent to the AM deposition process. TRIP steels have the potential to greatly enhance toughness while maintaining high strength and tolerate the porosity from AM. A parametric design approach utilizing CALPHAD methods and process-structure-property modeling was employed to computationally optimize composition and processing. The TRIP steel design presents high strength, optimal austenite stability, and solidification characteristics like known printable steels. An overview of the design approach, key modeling, and final properties of interest will be discussed.
