The features of the technical preparation of the process of isothermal stamping of a monowheel are considered. The technological process of manufacturing solid stamped impellers (monowheels) of a gas turbine engine by high-speed milling is highly labor-intensive and has a low metal utilization factor. The most promising technological process for manufacturing such parts is isothermal stamping, which allows for favorable formation of the material texture in the body of the disk and blade. An assessment of the features of metal movement during isothermal stamping of a monowheel with axial arrangement of blades is presented using the Deform-3D software package. The energy-power parameters and the stress-strain state at different stages of the formation of a monowheel made of AMg6 alloy are established. A typical stamp and installation for isothermal stamping are developed. Experimental work on isothermal stamping of a monowheel with axial arrangement of blades made of AMg6 alloy is carried out and the mechanical properties of the forging after isothermal stamping are determined. Static tests were conducted to assess the mechanical properties of the material forging a monowheel with axial thin-walled elements after isothermal stamping. The results of hardness measurements showed a slight decrease in microhardness from 115 to 104 HV when the stamped monowheel with axial thin-walled elements was removed from the axis.
