Pattern formation during melting of lamellar eutectics
Rahul Nellissery Rajan, Rajesh Kumari Rajendran, Guillaume Boussinot +3
We present a study of the melting dynamics of a two-phase eutectic solid. In situ, thin-sample experiments using a transparent eutectic alloy and two-dimensional phase field simula…
From irregular to regular eutectic growth in the Al-Al3Ni system: in situ observations during directional solidification
Paul Chao, Shanmukha Kiran Aramanda, Xianghui Xiao +3
We investigate the irregular eutectic growth dynamics of the Al-Al3Ni alloy, in which one of the solid phases (Al3Ni) grows faceted from the liquid. Leveraging in situ optical micr…
Phase boundary anisotropy and its effects on the maze-to-lamellar transition in a directionally solidified Al-Al2Cu eutectic
Ulrike Hecht, Janin Eiken, Silvère Akamatsu +1
Solid-solid phase boundary anisotropy is a key factor controlling the selection and evolution of non-faceted eutectic patterns during directional solidification. This is most remar…
Influence of morphological instability on grain boundary trajectory during directional solidification
Supriyo Ghosh, Alain Karma, Mathis Plapp +3
The interplay between the diffusion-controlled dynamics of a solidification front and the trajectory of a grain boundary groove at the solid-liquid interface is studied by means of…
Weakly faceted cellular patterns versus growth-induced plastic deformation in thin-sample directional solidification of monoclinic biphenyl
Tamas Borzsonyi, Silvere Akamatsu, Gabriel Faivre
We present an experimental study of thin-sample directional solidification (T-DS) in impure biphenyl. The plate-like growth shape of the monoclinic biphenyl crystals includes two l…
Hexagonal eutectic solidification patterns operating near a marginal stability point
Mikael Perrut, Silvère Akamatsu, Sabine Bottin-Rousseau +1
We study the long-time dynamics of hexagonal directional-solidification patterns in bulk samples of a transparent eutectic alloy using an optical method which permits real-time obs…
