WebThe meaning of SOLVUS is a curve on a temperature-composition diagram indicating the limits of solubility of one solid phase in another. a curve on a temperature-composition … 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.
WebWhen the aluminum-copper alloy of less than 5 wt% copper is heated to a temperature just above the solvus line, only one phase (kappa, ) is thermodynamically stable. Other solid phases dissolve (disappear). This process is called solution treatment. The only requirement is that the specimen must be kept at this temperature for a long enough time.
