| Abstract Scope |
Additive manufacturing (AM) unlocks new design space for material microstructures by allowing multi-material or compositionally graded structures. These can contain combinations of metals that are incompatible by traditional manufacturing techniques. The range of solidification and cooling rates accessed by various AM technologies can potentially access an array of microstructures with widely different properties even in materials that are compositionally identical. Here, we use the gradient between vanadium and stainless steel as a model system to demonstrate an array of different microstructures. These include both brittle intermetallic compounds and robust solid-solution phases. We use CALPHAD tools to model the phase behavior as a function of composition and thermal history to predictively select manufacturing pathways that will yield graded parts with beneficial properties. |
