Common heat treatment processes for NS112 alloy:
1.Solution treatment: Solution treatment is to heat the alloy to its solution temperature, hold it for a period of time, so that the solution elements in the alloy are evenly distributed in the grains, and then fix the structure through rapid cooling to improve the plasticity and toughness of the alloy. Solution treatment helps to remove precipitate phases and grain boundary precipitation from the alloy and improve the processing properties of the alloy.
2.Aging treatment: Aging treatment is to heat the alloy to a lower temperature after solution treatment and hold it for a certain period of time to promote the precipitation of solute elements in the solid solution to form a strengthening phase, so as to improve the strength and heat resistance of the alloy. Aging helps to adjust the strength and hardness of the alloy, improving its oxidation and heat resistance.
3.Annealing: Annealing is the process of heating the alloy to a higher temperature and then cooling it at an appropriate rate, with the aim of eliminating work hardening and stress, and improving the plasticity and machinability of the alloy.
4.Stress relieving: Stress annealing is to reduce the residual stress accumulated by the alloy during machining, reduce the brittleness of the alloy and improve its stability.
