Solution treatment is the heating of an alloy to a suitable temperature, holding it at that temperature long enough to cause one or more constituents to enter into a solid solution and then cooling it rapidly enough to hold these constituents in solution. Subsequent precipitation heat treatments allow controlled release of these constituents either naturally (at room temperature) or artificially (at higher temperatures).
There are a multitude of cast and wrought nickel-based alloys that can have various desirable characteristics enhanced by either solution treating or by solution treating and precipitation age hardening. Characteristics such as room temperature and/or elevated temperature mechanical strength, corrosion resistance and oxidation resistance are typically enhanced by such heat treatments.
The properties of heat treatable nickel-based alloys can be enhanced by selection of appropriate heat treating parameters. The use of solution treating alone or solution treating followed by precipitation age hardening is commonly used with nickel-based alloys.
