[‚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.

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.
At the same time, the residual L1 after recalescence generated L2 phase between fibrous a(Cu) in the monotectic reaction.
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.
From the thermal point of view, an ideal grain refiner would remove the recalescence entirely [34-36].
In the solidification process, there are two recalescence peaks because the latent heat release rate of phase change is much higher than heat dissipation.
Subsequent heating of the tubes by fresh molten aluminum then caused recalescence. As a result, the center of the casting was becoming a hot spot, which fed the solidifying metal around the outside of the casting.
[17] on the effects of Sr and solidification rate on eutectic grain structure in an Al-13wt% Si alloy revealed that the characteristic temperature of eutectic nucleation ([T.sub.N]), the minimum temperature prior to recalescence [([T.sub.M]), and the growth temperature (TG) during cooling as determined by quantitative thermal analysis are continuously decreased with increasing Sr content.
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.
[14] on the effects of Sr and solidification rate on eutectic grain structure in an Al-13wt.% Si alloy revealed that the characteristic temperature of eutectic nucleation ([T.sub.N]), the minimum temperature prior to recalescence ([T.sub.M]), and the growth temperature ([T.sub.G]) during cooling as determined by quantitative thermal analysis are continuously decreased with increasing Sr content.
