The MaterialDigital initiative represents a major driver toward the digitalization of material science. Next to providing prototypical infrastructure required for building shared data space and working on semantic interoperability data, core focus area Platform (PMD) is utilization workflows encapsulate processing simulation steps in accordance with findable, accessible, interoperable, reusable principles. In collaboration funded projects initiative, workflow group strives establish...
Abstract We propose a novel finite element-based physics-informed operator learning framework that allows for predicting spatiotemporal dynamics governed by partial differential equations (PDEs). The Galerkin discretized weak formulation is employed to incorporate physics into the loss function, termed (FOL), along with implicit Euler time integration scheme temporal discretization. A transient thermal conduction problem considered benchmark performance, where FOL takes temperature field at...
Laser-based additive manufacturing offers a promising route for 3D printing of metallic parts. We evidence experimentally particular columnar solidification microstructure in Laser Powder-Bed Fusion processed Inconel 718 nickel-based alloy, that we interpret using phase-field simulations and classical dendritic growth theories. Owing to the large temperature gradient cooling rate, takes places through arrays wherein characteristic length scales, i.e tip radius, diffusion primary spacing, are...
Thermo-physical data of the semi-solid region in directionally solidified materials are difficult to obtain by experiments, but at same time high importance for prediction casting defects like freckles, hot-tears, or micro-porosity, and further provide input mesoscopic macroscopic models. This paper shows how phase fractions, compositions, enthalpies, densities, as well melt permeability can be obtained whole range between liquidus solidus temperature, an integral alloy-specific freckle risk...
Eutectic alloys offer great promises for additive manufacturing owing to an enhancement of mechanical properties due ultra-fine eutectic microstructures. We study experimentally and numerically through phase-field simulations the Laser Powder-Bed Fusion processing several near-eutectic Al–Ni alloys. The large variations cooling rate within melt pool allow us investigate dependence selected microstructure on concentration alloy solidification velocity. find that coupled zone, i.e....
In this paper, the effect of particle pinning on grain boundary motion is investigated by phase-field modeling. general, kinetics growth in multicrystalline materials determined interplay curvature driven and balance interfacial tension at vertices a network. A comprehensive way to treat both effects one model given approach. The specific feature multiphase-field used for investigation its ability each or phase with individual characteristics, together thermodynamic coupling which allows...

Thin silicon films are of great importance for large-area electronic applications, example, as the basis switching electronics in flat-panel display devices or active layer solar cells. In this paper, we show that nanoparticles have potential to be used raw material further processing toward a microcrystalline film. This can done by thermal treatment with reduced budget because melting point is much lower only 60% equilibrium temperature silicon. Coagulation processes liquid droplets then...
