recalesce

The metal begins to recalesce as it cools.

Definition

1. Verb (intransitive):
   • To become hot again: "recalesce" refers to the phenomenon in which a metal, especially steel or iron, emits a sudden glow of heat after cooling to a certain point, as a result of an exothermic phase change (e.g., from austenite to ferrite or cementite). This term is primarily used in metallurgy.

Usage Examples

• (The metal suddenly became hot again due to a phase change.)
• (The metal glows again during cooling.)

Advanced Usage

• "Recalescence point": the specific temperature at which a metal recalesces.
  • The recalescence point of pure iron occurs at approximately 768°C. (The temperature where the glow appears.)
• "Recalescence curve": a graph showing temperature changes during cooling, including the recalescence event.
  • The recalescence curve of steel helps identify its phase transitions. (A plot of temperature over time.)

Variants and Related Words

• Recalescence (noun): the act or process of recalescing; the sudden glow emitted by a metal during cooling.
  • The recalescence of the steel was observed during the experiment. (The glowing phenomenon.)
• Recalescent (adjective): relating to or characterized by recalescence.
  • The recalescent behavior of the alloy was studied in detail. (The property of glowing again.)

Synonyms

• Reheat: to heat again (general term, but not specific to metallurgical phase changes).
• Glow: to emit light or heat (less technical, broader meaning).

Phrasal Verbs

• None directly applicable; "recalesce" is a technical verb and is not commonly used in phrasal verb constructions.
