recalescence

re·ca·les·cence

 (rē′kə-lĕs′əns)
n.
A sudden glowing in a cooling metal caused by liberation of the latent heat of transformation.

[From Latin recalēscēns, recalēscent-, present participle of recalēscere, to grow warm again : re-, re- + calēscere, to become warm, inchoative of calēre, to be warm; see kelə- in Indo-European roots.]

re′ca·les′cent adj.

recalescence

(ˌriːkəˈlɛsəns)
n
(Metallurgy) a sudden spontaneous increase in the temperature of cooling iron resulting from an exothermic change in crystal structure occurring at a particular temperature
[C19: from Latin recalēscere to grow warm again, from re- + calēscere, from calēre to be hot]

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.

When recalescence 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.
