Phase-field modeling of radiation-induced composition redistribution: An application to additively manufactured austenitic Fe-Cr-Ni
Sourabh Bhagwan Kadambi, Daniel Schwen, Jia-Hong Ke +2
Multicomponent alloys undergoing irradiation damage develop radiation-induced composition redistribution at point defect sinks such as grain boundaries (GBs) and dislocations. Such…
Phase Field Benchmark Problems for Dendritic Growth and Linear Elasticity
Andrea M. Jokisaari, Peter W. Voorhees, Jonathan E. Guyer +2
We present the second set of benchmark problems for phase field models that are being jointly developed by the Center for Hierarchical Materials Design (CHiMaD) and the National In…
Predicting the morphologies of γ' precipitates in cobalt-based superalloys
Andrea M. Jokisaari, Shahab S. Naghavi, Chris Wolverton +2
Cobalt-based alloys with γ/γ' microstructures have the potential to become the next generation of superalloys, but alloy compositions and processing steps must be optimized to impr…
Zirconia and hafnia polymorphs -- ground state structural properties from diffusion Monte Carlo
Hyeondeok Shin, Anouar Benali, Ye Luo +5
Zirconia (zirconium dioxide) and hafnia (hafnium dioxide) are binary oxides used in a range of applications. Because zirconium and hafnium are chemically equivalent, they have thre…
Topological phase transformations and intrinsic size effects in ferroelectric nanoparticles
John Mangeri, Yomery Espinal, Andrea Jokisaari +3
Composite materials comprised of ferroelectric nanoparticles in a dielectric matrix are being actively investigated for a variety of functional properties attractive for a wide ran…
Benchmark Problems for Numerical Implementations of Phase Field Models
A. M. Jokisaari, P. W. Voorhees, J. E. Guyer +2
We present the first set of benchmark problems for phase field models that are being developed by the Center for Hierarchical Materials Design (CHiMaD) and the National Institute o…
