Phase-field simulation of solidification dendritic segregation in Ti-45Al alloy [PDF]

China Foundry, 2017
The microstructures and mechanical properties of TiAl alloys are directly linked to micro-segregation which cannot be avoided during solidification.

Magnetic Phase Diagram of the Ferromagnetically Stacked Triangular XY Antiferromagnet: A Finite-Size Scaling Study

, 1993
Histogram Monte-Carlo simulation results are presented for the magnetic-field -- temperature phase diagram of the XY model on a stacked triangular lattice with antiferromagnetic intraplane and ferromagnetic interplane interactions.

Field-driven topological glass transition in a model flux line lattice

, 1996
We show that the flux line lattice in a model layered HTSC becomes unstable above a critical magnetic field with respect to a plastic deformation via penetration of pairs of point-like disclination defects.

Phase Field Modelling of Submonolayer Epitaxial Growth

, 2010
We report simulations of submonolayer epitaxial growth using a continuum phase field model. The island density and the island size distribution both show scaling behavior.

Effective Scalar Field Theory for the Electroweak Phase Transition

, 1994
We investigate an effective model for the finite temperature restoration phase transition of the electroweak theory. It is obtained by dimensional reduction of the $3+1$ dimensional full theory and by subsequent integration over all static gauge degrees ...

Effect of Ni alloying on the microstructural evolution and mechanical properties of two duplex light-weight steels during different annealing temperatures: Experiment and phase-field simulation

, 2017
This paper presents a study of two lightweight steels, Fe-15Mn-10Al-0.8C-5Ni and Fe-15Mn-10Al-0.8C (in wt.%) where strength is dependent upon the microstructure of 2 nd phase precipitates.

Relativistic electron beam driven longitudinal wake-wave breaking in a cold plasma

, 2016
Space-time evolution of relativistic electron beam driven wake-field in a cold, homogeneous plasma, is studied using 1D-fluid simulation techniques. It is observed that the wake wave gradu- ally evolves and eventually breaks, exhibiting sharp spikes in ...

Numerical Simulation on Flow Field of Oilfield Three-Phase Separator

Journal of Applied Mathematics, 2013
The conventional measurement method can no longer guarantee the accuracy requirement after the oilfield development entering high water cut stage, due to the water content and gas phase in the flow.

Ordered Phase of the Dipolar Spin Ice under [110]-Magnetic Fields

, 2004
We find that the true ground state of the dipolar spin ice system under [110]-magnetic fields is the ``Q=X'' structure, which is consistent with both experiments and Monte Carlo simulations.
