Today's manufacturing processes are pushed to their limits to generate products with ever- increasing quality at low costs. A prominent hurdle on this path arises from the multiscale …
In the current work we employ multi-phase-field simulations to understand the effect of remelting on microstructure evolution, especially on nucleation of new grains during …
A unified thermodynamic description of moving non-equilibrium interfaces is developed for both solid/solid and solid/liquid transformations. The theory is applicable to concentrated …
Nucleation and grain growth during metal additive manufacturing (AM) still remain debatable since the nature of rapid melting and solidification induced by laser-powder …
In this work, we present phase-field (PF) simulations directly coupled to thermodynamic and kinetic databases in three dimensions. The direct coupling allows consideration of the full …
The process parameters used for building a part utilizing the powder-bed fusion (PBF) additive manufacturing (AM) system have a direct influence on the quality—and therefore …
An integrated simulation framework consisting of the 3D finite element method and 3D cellular automaton method is presented for simulating the multi-track and multi-layer …
The integrity of the final printed components is mostly dictated by the adhesion between the particles and phases that form upon solidification, which is a major problem in printing …
Predicting the melt pool's various characteristics and developing a reliable correlation between these melt pool characteristics and powder bed fusion (PBF) process parameters is …
