The solvus temperature
WebThe alloy is heated above the solvus temperature to dissolve any second phase and to produce a homogeneous single-phase structure. Solvus - A solubility line that separates a single solid phase region from a 2 solid phase region in the phase diagram. WebJan 25, 2024 · However, the solid solution is now supersaturated with copper and there is a driving force for precipitation of the equilibrium θ phase. If the alloy is subsequently aged at a temperature between ambient and 180° C (the GP zone solvus), the first precipitate to nucleate is not θ but coherent Cu-rich GP zones.
