Abstract

A physical simulation method for a forging process of a nickel-base superalloy includes: subjecting a nickel-base superalloy sample to heating, heat preservation, and quenching successively to obtain a pretreated sample; and subjecting the pretreated sample to heating, first heat preservation, cooling, repeated compression-cooling treatments, second heat preservation, and quenching successively to obtain a simulated sample, where the compression-cooling treatments are repeated at least three times. In the physical simulation method, multi-pass compression-cooling deformation is adopted to simulate a forging process of a nickel-base superalloy, and this forging simulation method is close to an actual forging process, has an excellent simulation effect and high operability, and involves simple operations. The physical simulation method is suitable for a variety of nickel-base superalloys of a same forging method. The simulated sample is not much different from a same part of a forging obtained after actual forging in terms of a structure and hardness.
