recrystallization

  1. (chemical): The repeated dissolution and precipitation of a solid from a liquid solvent.
  2. (metallurgical): The process in which a crystalline solid with a high degree of disorder develops a new microstructure by the nucleation of relatively imperfection-free regions, and their propagation throughout the complete solid.
