We present a workflow that combines atomistic, phase-field and FEM simulations to study the effects of alloy composition and of manufacturing process on the working performance of a component.
In this approach, a component-scale FEM model of the manufacturing process captures the effect of process parameters and produces the inputs for a phase-field simulation of microstructural evolution. From the phase field method, an RVE of the microstructure is generated and introduced into an FEM micro-mechanical simulation to assess the mechanical potential of the microstructure produced. The workflow also produces homogenized properties for a macro-scale structural performance analysis of the component.
We use first-principle calculations to assess the effects of alloy composition on performance by calculating the properties needed in the macro and meso-scale manufacturing simulations. We illustrate the workflow by simulating additive manufacturing of β stable Titanium alloys.
