Numerical Simulations of Coarsening of Lamellar Structures: Applications to metallic alloys

Understanding the microstructural evolution in metallic alloys helps to control their properties and improve their performance in industrial applications. The emphasis of our study is the coarsening mechanisms of lamellar structures. Coarsening of lamellar structure is modeled numerically using Monte Carlo Potts method. The initial microstructure consists of alternating lamellae of phase A and ...

Three-dimensional phase-field simulations of coarsening kinetics of c0 particles in binary Ni–Al alloys

The coarsening kinetics of c0 precipitates in binary Ni–Al alloy is studied using three-dimensional (3D) phase-field simulations. The bulk thermodynamic information and atomic diffusion mobilities are obtained from databases constructed using the CALPHAD approach, while the experimental values for the interfacial energy, elastic constants and lattice mismatch are directly employed in the phase-...

Coarsening resistance at 400 C of precipitation-strengthened Al–Zr–Sc–Er alloys

The effect of substituting 0.01 or 0.02 at.% Er for Sc in an Al–0.06 Zr–0.06 Sc at.% alloy was studied to develop cost-effective high-temperature aluminum alloys for aerospace and automotive applications. Spheroidal, coherent, L12-ordered Al3(Sc, Zr, Er) precipitates with a structure consisting of an Er-enriched core surrounded by a Sc-enriched inner shell and a Zr-enriched outer shell (core/do...

Interface preserving coarsening multigrid for elliptic problems with highly discontinuous coefficients

We propose an interface preserving coarsening, a geometric technique for solving discontinuous coefficient partial differential equations by multigrid. It selects coarse grid points so that all the coarse grids are aligned with the interfaces for regular interface problems on structured grids, and so that the interfaces are resolved as much as possible for irregular interface problems. As a res...

Coarsening fronts

We characterize the spatial spreading of the coarsening process in the Allen-Cahn equation in terms of the propagation of a nonlinear modulated front. Unstable periodic patterns of the Allen-Cahn equation are invaded by a front, propagating in an oscillatory fashion, and leaving behind the homogeneous, stable equilibrium. During one cycle of the oscillatory propagation, two layers of the period...
