A vacuum solution and aging treatment process for improving high-temperature plasticity of GH4738 rings includes: heating a GH4738 ring to 1020&#xb0; C. to 1030&#xb0; C. in a vacuum environment; injecting nitrogen; subjecting the GH4738 ring to aging treatment at 740&#xb0; C. to 750&#xb0; C.; and taking out and air-cooling the GH4738 ring. The method realizes the uniform distribution of the intragranular &#x3b3;' precipitates and the intergranular MCcarbides in the GH4738 ring after heat treatment. The elongation and area reduction of the alloy ring stretched at 540&#xb0; 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&#xb0; 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.
