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…
