  • Patent number: 11807930
    Abstract: A vacuum solution and aging treatment process for improving high-temperature plasticity of GH4738 rings includes: heating a GH4738 ring to 1020° C. to 1030° C. in a vacuum environment; injecting nitrogen; subjecting the GH4738 ring to aging treatment at 740° C. to 750° C.; and taking out and air-cooling the GH4738 ring. The method realizes the uniform distribution of the intragranular ?? precipitates and the intergranular M23C6 carbides in the GH4738 ring after heat treatment. The elongation and area reduction of the alloy ring stretched at 540° C. after heat treatment are 30% and 34% respectively, which are 25% and 36% higher than those before process optimization respectively; and that at 760° C. are 49% and 70% respectively, which are 32% and 27% higher than those before process optimization respectively. The index requirements can be fully met. This process is applicable to GH4738 rings, which have a high requirement on high-temperature plasticity after heat treatment.
