Solution annealing

Solution annealing is carried out to dissolve alloying elements in the matrix homogenously and to obtain uniform homogeneous microstructures and material properties. Ferrous materials are annealed within a temperature range of 950 to 1200 °C in Durferrit GS 960 or in Durferrit Glühkohle K. Non-ferrous metals are annealed within a temperature range of 460 to 540 °C in Durferrit AV salts. Depending on the material, annealing can be followed by a further treatment, the so-called ageing, for precipitation hardening.
