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…
Revisiting Jackson-Hunt calculations: Unified theoretical analysis for generic multi-phase growth in a multi-component system
Arka Lahiri, Abhik Choudhury
A straight-forward extension of the Jackson-Hunt theory for directionally solidifying multi-phase growth where the number of components exceeds the number of solid phases becomes d…
Theoretical and numerical investigation of diffusive instabilities in multi-component alloys
Arka Lahiri, Abhik Choudhury
Mechanical properties of engineering alloys are strongly correlated to their microstructural length scale. Diffusive insta- bilities of the Mullins-Sekerka type is one of the princ…
Eutectic colony formation in systems with interfacial energy anisotropy: A phase field study
Arka Lahiri, Chandrashekhar Tiwary, Kamanio Chattopadhyay +2
Instability of a binary eutectic solidification front to morphological perturbations due to rejection of a ternary impurity leads to the formation of eutectic colonies. Whereas, th…
