Response-function-optimized phase field modeling of solute trapping and solute drag in rapid alloy solidification
Joni Kaipainen, Tatu Pinomaa, Nikolas Provatas
Quantitative prediction of rapid-solidification microstructures requires phase field models that represent the velocity dependence of interfacial properties, including solute parti…
Deformation assisted precipitation in binary alloys: A competition of time-scales
Alex Mamaev, Duncan Burns, Nikolas Provatas
We consider the process of precipitation in binary alloys in the presence of mechanical deformation. It is commonly observed that mechanical deformation prior to or during precipit…
Generalizing the structural phase field crystal approach for modeling solid-liquid-vapor phase transformations in pure materials
Daniel L. Coelho, Duncan Burns, Emily Wilson +1
In a recent class of phase field crystal (PFC) models, the density order parameter is coupled to powers of its mean field. This effectively introduces a phenomenology of higher-ord…
LeapFrog: Getting the Jump on Multi-Scale Materials Simulations Using Machine Learning
Damien Pinto, Michael Greenwood, Nikolas Provatas
The development of novel materials in recent years has been accelerated greatly by the use of computational modelling techniques aimed at elucidating the complex physics controllin…
Multiscale analysis of crystal defect formation in rapid solidification of pure aluminium and aluminium-copper alloys
Tatu Pinomaa, Matti Lindroos, Paul Jreidini +6
Rapid solidification leads to unique microstructural features, where a less studied topic is the formation of various crystalline defects, including high dislocation densities, as…
Orientation gradients in rapidly solidified pure aluminum thin films: comparison of experiments and phase-field crystal simulations
Paul Jreidini, Tatu Pinomaa, Jörg M. K. Wiezorek +3
Rapid solidification experiments on thin film aluminum samples reveal the presence of lattice orientation gradients within crystallizing grains. To study this phenomenon, a single-…
