Slowly cool in furnace for 8 to 18 hours Annealing atmosphere: inert gas such as argon gas, reducing gas such as hydrogen gas By the way, if the heating time is too long, the vibration absorbing performance may be deteriorated. If the heating time is too short, the annealing is insufficient and the vibration damping function cannot be secured. When the temperature is high, the heating time is shortened, and when the temperature is low, the heating time is lengthened to adjust the heating. If the slow cooling time in the furnace is too long, twins of the processed product are solidified and the vibration damping function is reduced, and if the slow cooling time in the furnace is short, the vibration damping function of the processed product is difficult to appear. Since M2052 is a manganese-based alloy, it is easily oxidized, and it is desirable to heat and slowly cool in an inert gas or a reducing gas. However, annealing in the air is also possible. In addition, slow cooling can be performed by air cooling or water cooling.

In some cases, the vibration damping property is restored by returning to the state before processing, or the structure grows to improve the vibration damping property from the original state.
