Emergence of rapid solidification microstructure in additive manufacturing of a Magnesium alloy
D. Tourret, R. Tavakoli, A. D. Boccardo +3
Bioresorbable Mg-based alloys with low density, low elastic modulus, and excellent biocompatibility are outstanding candidates for temporary orthopedic implants. Coincidentally, me…
Grain growth competition and formation of grain boundaries during solidification of hcp alloys
A. K. Boukellal, M. Sarebanzadeh, A. Orozco-Caballero +3
Grain growth competition during directional solidification of a polycrystal with hexagonal (hcp) symmetry (Mg-1wt%Gd alloy) is studied by phase-field modeling, exploring the effect…
Morphological stability of solid-liquid interfaces under additive manufacturing conditions
D. Tourret, J. Klemm-Toole, A. Eres Castellanos +18
Understanding rapid solidification behavior at velocities relevant to additive manufacturing (AM) is critical to controlling microstructure selection. Although in-situ visualizatio…
Cell Invasion during Competitive Growth of Polycrystalline Solidification Patterns
Younggil Song, Fatima L. Mota, Damien Tourret +5
Spatially extended cellular and dendritic array structures forming during solidification processes such as casting, welding, or additive manufacturing are generally polycrystalline…
Scaling laws for two-dimensional dendritic crystal growth in a narrow channel
Younggil Song, Damien Tourret, Alain Karma
We investigate analytically and computationally the dynamics of 2D needle crystal growth from the melt in a narrow channel. Our analytical theory predicts that, in the low supersat…
Multiscale prediction of microstructure length scales in metallic alloy casting
B. Bellón, A. K. Boukellal, T. Isensee +6
In this article, we combine casting experiments and quantitative simulations to present a novel multiscale modeling approach to predict local primary dendritic spacings in metallic…
Multiscale dendritic needle network model of alloy solidification with fluid flow
D. Tourret, M. M. Francois, A. J. Clarke
We present a mathematical formulation of a multiscale model for solidification with convective flow in the liquid phase. The model is an extension of the dendritic needle network a…
