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…
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-…
Efficient and quantitative phase field simulations of polycrystalline solidification using a vector order parameter
Tatu Pinomaa, Nana Ofori-Opoku, Anssi Laukkanen +1
A vector order parameter phase field model derived from a grand potential functional is presented as a new approach for modeling polycrystalline solidification of alloys. In this a…
Quantitative phase field modeling of solute trapping and continuous growth kinetics in rapid solidification
Tatu Pinomaa, Nikolas Provatas
Solute trapping is an important phenomenon in rapid solidification of alloys, for which the continuous growth model (CGM) is a popular sharp interface theory. Using matched asympto…
d0 Ferromagnetic Interface Between Non-magnetic Perovskites
R. Oja, M. Tyunina, L. Yao +8
We use computational and experimental methods to study d0 ferromagnetism at a charge- imbalanced interface between two perovskites. In SrTiO3/KTaO3 superlattice calculations, the c…
