Title: Three-dimensional multiscale modeling of dendritic spacing selection during Al-Si directional solidification

Abstract

We present a three-dimensional extension of the multiscale dendritic needle network (DNN) model. This approach enables quantitative simulations of the unsteady dynamics of complex hierarchical networks in spatially extended dendritic arrays. We apply the model to directional solidification of Al-9.8 wt.%Si alloy and directly compare the model predictions with measurements from experiments with in situ x-ray imaging. The focus is on the dynamical selection of primary spacings over a range of growth velocities, and the influence of sample geometry on the selection of spacings. Simulation results show good agreement with experiments. Here, the computationally efficient DNN model opens new avenues for investigating the dynamics of large dendritic arrays at scales relevant to solidification experiments and processes.

Figure 1 Figure 1: The Dendritic Needle Network model represents a dendritic grain, like the ammoniumbromide crystal from Ref. [35] in (a), as a hierarchical network of needle-like branches interacting through the long range diffusion field, as illustrated in (b). The instantaneous tip radius ρ(t) and velocity V (t) of each branchmore » is established by combining two conditions at distinct length scales: (c) a solute conservation condition at an intermediate scale larger than the tip radius ρ, but smaller than the diffusion length D/V , and (d) a solvability condition at the scale of the tip radius ρ.« less
