Isothermal annealing: The workpiece is heated to a higher temperature sufficient for recrystallization to be cooled, and then cooled to a temperature at which the β phase has high stability (this temperature is generally lower than the recrystallization temperature), maintained at this temperature, and then cooled in air.
Compared with simple annealing, the visual observation of the second stage of heat preservation is to fully decompose the β phase, to make the β phase in a stable state, to stabilize the properties and structure of the titanium alloy, and to make the titanium alloy have a relatively high shape and heat. Stability and durability. Therefore, isothermal annealing is suitable for α+β type alloys with higher β content.
