Interface structures and load-bearing mechanical properties in additively manufactured metallic functionally graded materials

Popis výsledku v původním jazyce

Metallic functionally graded materials (FGMs) offer a transformative solution for aerospace, automotive, and energy applications, where components must endure dynamic loads and extreme environments. Additive manufacturing (AM), particularly directed energy deposition (DED), enables precise control over compositional and microstructural gradients in these materials. However, the relationship between AM process parameters, interface structure, and key mechanical properties such as fatigue, creep, and fracture remains not fully understood. This review critically examines how AM variables such as laser power, deposition strategy, heat treatment, and thermal gradients affect interface formation and stability in metallic FGMs. By linking interface features (e.g., compositional transition, residual stress, and phase stability) to load-bearing behaviour, the connection between microstructure and mechanical performance is clarified. The review also synthesizes recent experimental and modelling advances, proposing practical strategies for interface engineering. These insights facilitate the design of next-generation metallic FGMs with enhanced mechanical reliability for extreme service environments.
