[‚rē·kə′les·əns]
(metallurgy)
Brightening (reglowing) of iron on cooling through the gamma- to alpha-phase transformation temperature caused by liberation of the latent heat of transformation.

9) However, the recalescence stage is still not well understood in terms of the initiation mechanism.
Further understanding of the recalescence stage for undercooled liquid, in terms of dynamics and structure, could possibly unveil a strong influence of this stage on solidification of static or spreading drops.
The relevant thermal parameters were liquidus temperature, lowest eutectic temperature, the recalescence, solidus, graphite factor 1, graphite factor 2, cooling rate at solidus, and eutectoid temperature.
This region develops during the recalescence plateau (point C), and the solute buildup process begins and finishes very quickly at point D.
Obviously, no recalescence is observed here since the cooling rate is prescribed and the polymer is assumed to follow the imposed temperature.
Data on recalescence indicated that only SiC, alone or mixed with 75% ferrosilicon, and FeS had a beneficial effect leading to a decrease in recalescence in both base and ductile irons (Fig.
When comparing the effects of metallurgical additions on recalescence versus nodule count, data showed that the nodule count generally increased as the recalescence decreased and vice-versa.
Both maximum and minimum eutectic temperatures should be as high as possible, and the maximum recalescence rate should be reduced.
Type and amount of inoculant can be optimized, for example, by studying the effect on the recalescence and the high eutectic temperature.
Occasionally, there will be an unexpected recalescence in a tellurium cup.
Well-inoculated iron will typically have a recalescence from 6-10F- (3-5C).
