Supplementary Data to "Simulation of dendritic-eutectic growth with the phase-field method" by Seiz et al.

Video files for several simulations conducted for the paper, showing more of the dynamic time evolution than possible in the paper itself.

Update 24/04/2023: A few additional simulations were conducted to test for the applicability of the theory delineating the dendritic-eutectic regime from the eutectic regime. Videos of these plus some additional data is deposited at

https://zenodo.org/record/7858461

All videos show the Cu composition field, with the color ranging from 0.02 (pure black) to 0.33 (pure white).
Thus black represents the fcc Al crystal, whitish-grey the Al2Cu intermetallic phase and grey shades in between the liquid melt, with lighter shades being richer in Cu.
Excluding the complete directional solidification videos (full*webm), all videos show regions of 280x250um^2, with the far-field to the right being cut off to emphasize the structure.

{close,far}_d+e.webm:
Complete simulations resulting in a eutectic structure either growing close to the dendrite tip or far from it, cropped to slightly above the solidification front.
The same speed v=160um/s and melt composition c_0=0.12 are used, but two different gradients: 99K/mm for close growth and 24.7K/mm for far growth; at the even smaller gradient the eutectic is no longer in the moving window.

traveling_oscillation.webm:
Complete simulation resulting in a eutectic with traveling oscillations. (v=160um/s, c_0=0.13, G=6.18K/mm)

jump_d+e_e.webm:
Jumps from v = 160um/s to 320um/s at simulation start in order to move from a dendritic-eutectic morphology to a eutectic morphology.
After a eutectic morphology is obtained, the jump is reversed (around 17s into the video) and only a coarsening of the eutectic is observed.

jump_e_d+e.webm:
Jumps from v=320um/s to 20um/s at simulation start in order to move from a eutectic morphology to a dendritic-eutectic morphology.

full_cropped*webm:
Complete directional solidification for different alloy compositions and processing conditions yielding different structures. Cropped to slightly above the final maximum position of any solid phase, showing a 970x500um^2 domain.
A scaling to 50% of the original resolution is performed as some players/browsers have trouble with large resolutions.
e: primarily eutectic (v=320um/s, G=24.7K/mm, c_0 = 0.12)
d+e: dendritic-eutectic (v=160um/s, G=24.7K/mm, c_0 = 0.12)

full_d.webm:
Same as above, only non-cropped as the structure fills the entire simulation box (1500x500um^2). (v=320um/s, G=24.7K/mm, c_0 = 0.08)
