  rdf:value "A heat treatment process in which a material is heated to a specific temperature, held at that temperature for a designated period, and then cooled at a controlled rate (typically slowly) to induce structural changes such as grain growth, reduction of dislocation density, relief of internal residual stresses, or alteration of phase composition."@en ;
  skos:example "The steel component underwent annealing to improve its ductility and reduce the hardness induced by the previous cold-working steps."@en ;
