Using an IR camera, we observed that the solidification initiation of the main drop, which corresponds to the supercooling stage duration, is triggered by the erratic wave-like recalescence
front of the surrounding condensed microdrops.
All lanthanum additions led to the development of significant recalescence
prior to eutectic growth; no recalescence
was observed in the alloy at high levels of cerium additions.

is observed, the furnace temperature is set to within 1 K below the freezing-point temperature.
First, the recalescence
phenomenon, where the temperature rises due to the latent heat release, is well illustrated and a substantial temperature plateau develops immediately after the recalescence
Thermal analysis data were recorded to determine under-cooling and recalescence
They reported higher primary graphite arrest in irons treated with sulfur while the eutectic and recalescence
parameters remained unchanged.
The system, which is based on advanced thermal analysis, not only calculates metallurgical attributes such as liquidus, eutectic, recalescence
, cooling rate, active carbon equivalent and 20 more but also interprets the data.
Subsequent heating of the tubes by fresh molten aluminum then caused recalescence
Other parts of the cooling curve that respond to inoculation are the start of eutectic freezing, maximum recalescence
rate (the difference between eutectic extremes) and the first derivative at solidus.
The maximum recales-cence rate (TEM) shouldn't be too high and the recalescence
between 36-41F (2-5C).
An early recalescence
(glowing on the metal surface) indicates nodularity, while a late recalescence
at a lower temperature indicates flake graphite.
