... of the diagram can absorb much more of the solute metal at elevated temperature than it can at room temperature. When the alloy is heated to the solution heat treating temperature and held for a sufficient length of time, the solvent metal absorbs some of the solute metal. Then, when it is rapidly cooled to room...

... to treat nonferrous alloys is annealing. The annealing practice typically consists of heating the material to a sufficiently high temperature to soften it so that it can safely undergo further processing or be used in application. For example, cold-worked alloys are annealed to soften the worked alloy...
