Like annealing in general, solution annealing consists of 3 phases: heating, holding and cooling. In the case of ferrous materials, the solution temperature is in the range from 950 to 1,200°C. In contrast, the temperature during solution annealing of non-ferrous metals is significantly lower. It is between 460 and 540 ° C. After heating and holding, the material is cooled particularly quickly to room temperature during solution heat treatment. This process takes place using a special cooling gas. Depending on the material and the desired result, the cooling time can vary slightly.
