Dictionary – Solution Treatment

When solution/precipitation/aging grades of alloys are manufactured any working (e.g. rolling) or time (aging) hardens the material, this reduces formability and machinability of the metal

Solution treating restores the processibility of the material and is it is followed by precipitation hardening or controlled aging which develops the final resilience, uniformity & strength required of the finished product

After solution treating the strength giving alloying elements are truly dissolved in the parent metal (a solid solution). With precipitation treatment the elements are brought out of solution to form particular microscopic structures within the metal that increase properties such as hardness & tensile strength in the final product
