recalescence
[ad. L. recalēscĕre: see re- 2 c and calescent.]
The temporary generation of heat associated with a change in crystal structure when a solid is cooled through a transformation temperature (sometimes sufficient to produce a brief rise in temperature). So recaˈlesce v. intr.; recaˈlescent a.
1873W. F. Barrett in Phil. Mag. XLVI. 477 Wherever the momentary expansion of the wire is feeble or absent, there likewise this recalescence, as it might be termed, is also feeble or absent. 1887Nature 15 Dec. 165 If an iron bar..be heated to a white heat and allowed to cool, the brightness at first diminishes, and then reglows (recalesces) for a short interval. 1887Tomlinson Recalescence of Iron in Proc. Physical Soc. (1888) Apr. 107 The metal, to all appearances, receives a sudden accession of heat, and reglows. This phenomenon was discovered by Professor Barrett, and is frequently designated the ‘recalescence’ of iron. 1899W. F. Barrett in Nature 22 June 173 In this paper, the phenomenon, for which I suggested the name recalescence, was first described. 1912,1916[see decalescence]. 1973J. G. Tweeddale Materials Technol. II. ii. 15 Once nucleation is really started solidification may proceed quite quickly and is then likely to be associated with release of thermal energy as recalescence. |
