Zusammenfassung:The invention relates to the field of heat treatment, in particular to a method for adjusting the yield strength of a high-quality GH2132 alloy blade forging. The problem that the yield strength in the prior art is low is solved. The yield strength obtained after heat treatment of the forging is adjusted to meet the technical requirement. According to a heat treating regime, solution treatment and aging treatment are included; the temperature in solution treatment is 900 DEG C+/-10 DEG C and is kept for 1 h-2 h; after solution treatment, a PAG organic polymer water-soluble quenching medium KR6480 is adopted for cooling to room temperature; aging treatment of two times is adopted, wherein in aging temperature of the first time, the temperature is 705 DEG C+/-10 DEG C and is kept for 15-17 h, and air cooling is carried out to room temperature; and in aging treatment of the second time, the temperature is 650 DEG C+/-10 DEG C and is kept for 15-17 h, and air cooling is carried out to room temperature. GH2132 alloy is applied to an aero-engine, and the technology can be applied to the GH2132 alloy blade forging and can also be popularized in development and production of other parts of the material.
