Abstract Scope |
Additive Manufacturing (AM) revolutionized the manufacturing of complex
geometry products, especially in medical and aerospace fields. High-strength precipitate hardened (PH) stainless steels provide unique properties in term-of strength and corrosion resistance for critical applications in both fields. In the current study, a 3D multiple-slip crystal-plasticity dislocation-densities based model is used to study the effect of copper precipitate hardening in high-strength stainless steels. The proposed approach accurately predicts the complex structure of martensite and properly represents the precipitates, based on its characteristics, such as: texture, morphology, secondary phases and initial-dislocations-densities. The results show the effect of materials’ characteristics on mechanical properties and failure of AM-PH high-strength steels. The current work lays the groundwork for more extensive work of AM modeling. |
