Mapping of Microstructure Transitions during Rapid Alloy Solidification Using Bayesian-Guided Phase-Field Simulations
José Mancias, Brent Vela, Juan Flórez-Coronel +4
This study addresses microstructure selection mechanisms in rapid solidification, specifically targeting the transition from cellular/dendritic to planar interface morphologies und…
A particle-based approach for the prediction of grain microstructures in solidification processes
Salem Mosbah, Rodrigo Gómez Vázquez, Constantin Zenz +2
Grain microstructures are crucial to the mechanical properties, performance, and often lifetime of metallic components. Hence, the prediction of grain microstructures emerging from…
Phase-Field Study of Polycrystalline Growth and Texture Selection During Melt Pool Solidification
Rouhollah Tavakoli, Damien Tourret
Grain growth competition during solidification determines microstructural features, such as dendritic arm spacings, segregation pattern, and grain texture, which have a key impact…
On the occurrence of buoyancy-induced oscillatory growth instability in directional solidification of alloys
Josep Maria Barbera, Thomas Isensee, Damien Tourret
Recent solidification experiments identified an oscillatory growth instability during directional solidification of Ni-based superalloy CMSX4 under a given range of cooling rates.…
Grain growth competition during melt pool solidification -- Comparing phase-field and cellular automaton models
S. M. Elahi, R. Tavakoli, I. Romero +1
A broad range of computational models have been proposed to predict microstructure development during solidification processing but they have seldom been compared to each other on…
On the Effect of Nucleation Undercooling on Phase Transformation Kinetics
José Mancias, Vahid Attari, Raymundo Arróyave +1
We carry out an extensive comparison between Johnson-Mehl-Avrami-Kolmogorov (JMAK) theory of first-order phase transformation kinetics and phase-field (PF) results of a benchmark p…
Convective effects on columnar dendritic solidification -- A multiscale dendritic needle network study
Thomas Isensee, Damien Tourret
Gravity-induced buoyancy, inevitable in most solidification processes, substantially alters the dynamics of crystal growth, such that incorporating fluid flow in solidification mod…
Multiscale simulation of powder-bed fusion processing of metallic alloys
S. M. Elahi, R. Tavakoli, A. K. Boukellal +3
We present a computational framework for the simulations of powder-bed fusion of metallic alloys, which combines: (1) CalPhaD calculations of temperature-dependent alloy properties…
Comparing mesoscopic models for dendritic growth
Damien Tourret, Laszlo Sturz, Alexandre Viardin +1
We present a quantitative benchmark of multiscale models for dendritic growth simulations. We focus on approaches based on phase-field, dendritic needle network, and grain envelope…
Three-dimensional needle network model for dendritic growth with fluid flow
Thomas Isensee, Damien Tourret
We present a first implementation of the Dendritic Needle Network (DNN) model for dendritic crystal growth in three dimensions including convective transport in the melt. The numer…
