Role of interfacial energy and liquid diffusivities on pattern formation during thin-film three-phase eutectic growth
Sumeet Khanna, Abhik Choudhury
In this paper, we investigate three-phase eutectic growth during thin-film directional solidification of a model symmetric ternary eutectic alloy. In contrast to two-phase eutectic…
Formation of solid-state dendrites under the influence of coherency stresses: A diffuse interface approach
Bhalchandra Bhadak, Tushar Jogi, Saswata Bhattacharya +1
In this paper, we have formulated a phase-field model based on the grand-potential functional for the simulation of precipitate growth in the presence of coherency stresses. In par…
Phase-field modeling of equilibrium precipitate shapes under the influence of coherency stresses
Bhalchandra Bhadak, R. Sankarasubramanian, Abhik Choudhury
Coherency misfit stresses and their related anisotropies are known to influence the equilibrium shapes of precipitates. Additionally, mechanical properties of the alloys are also d…
Growth in multi-component alloys: Theoretical and numerical determination of phase concentrations
Arka Lahiri, T. A. Abinandanan, Abhik Choudhury +1
Understanding the role of solute diffusivities in equilibrium tie-line selection during growth of a second phase in ternary and higher multicomponent two phase alloys is an importa…
