利用有限元软件Deform对FGH96高温合金进行真空等温锻造过程模拟。通过对比不同工艺条件下物理场的变化情况，例如温度场、等效应变场等，从而确定合适的变形加工窗口，以保证在FGH96合金在真空等温锻造过程中始终处于一种稳定均匀变形的状态。

Utilizing the finite element software Deform, a simulation of the vacuum isothermal forging process for FGH96 superalloy was conducted. By comparing the variations in physical fields under different process conditions, such as temperature fields and equivalent strain fields, an appropriate deformation processing window was identified. This ensures that the FGH96 alloy remains in a stable and uniform deformation state throughout the vacuum isothermal forging process.
