Abstract

The invention discloses a device for preparing an alloy disc. The device comprises a sheath, wherein two baffles are movably mounted in the sheath; one end of each baffle is located outside the sheathand is fixedly connected with a handle; a powder discharging opening A and a powder discharging opening B are mounted on the upper surface of the sheath; the powder discharging opening A is located at one side of one baffle; the powder discharging opening B is located between the two baffles. The invention further discloses a method for preparing the alloy disc; a smart sheath structure design isused in a preparation process and synchronous filling of dissimilar metal powder is realized; the powder A and the powder B are sufficiently mixed through continuous vibration when the baffles are removed to form a transition region, so that the problem of weak connection after molding is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of alloy parts, and relates to a device for preparing alloy disc parts and a method for preparing alloy disc parts. Background technique [0002] With the further improvement of the thrust-to-weight ratio requirements of aerospace engines, the gas temperature at the hot end of aero-engines continues to rise, and the requirements for the working temperature and performance of superalloys are getting higher and higher. Excellent performance, more and more widely used in the hot end of the engine. [0003] At present, the working temperature in front of the turbine of advanced engines has reached as high as 1750°C, which requires alloy materials with high temperature bearing capacity and performance stability. Turbine discs used in aero-engines have a low working temperature at the center of the disc (hub), but they are correspondingly subjected to the torsion of the turbine shaft and require a fine-grained st...
