2.Cooling rate control: The cooling rate of Inconel 601 is also important after solution treatment. Cooling rate control is often used to reduce the formation of martensite in the alloy and avoid the formation of brittle structures.

3.Precipitation hardening: After solution treatment, precipitation hardening can be carried out to promote the precipitation of the precipitated phase in the alloy by controlling the temperature and time, and improve the hardness and strength of Inconel 601.

4.Tight control of time, temperature and cooling rate during heat treatment is key to ensuring consistent performance of Inconel 601. It is necessary to select the appropriate heat treatment process according to the chemical composition, engineering requirements and use environment of the specific alloy.
