The nickel-based powder superalloy has the characteristics of excellent high-temperature strength, creep resistance, fatigue resistance and good tissue stability, and has become the first choice material for manufacturing the turbine disk of the aeroengine with high thrust-weight ratio. The turbine disk of the aeroengine needs to work under complex stress and temperature conditions, the stress on the disk core is maximum, the stress is gradually reduced along the radial disk edge, the working temperature of the disk edge is highest, and the working temperature is gradually reduced towards the disk core along the radial direction. As aeronautical technology demands higher thrust-weight ratio performance of aeroengines, engine turbine disks are subjected to higher operating temperatures and stresses.
The core and the rim of the traditional turbine disk are made of the same material and subjected to heat treatment at the same time, so that the traditional turbine disk cannot have excellent yield strength and low-cycle fatigue performance of the core and excellent high-temperature creep and durability of the rim. The core of the powder superalloy turbine disk in the prior art is that the disk core and the disk edge of the turbine disk have different performances through the improvement of materials and processes so as to meet the working requirements of the disk edge and the disk core. The disc core and the disc edge of the scheme adopt the same alloy, the powder particle sizes are the same, the temperature rise of the disc core is restrained during solution heat treatment, the disc core grain growth is strictly controlled to enable the disc edge grain to be sufficiently grown, finally, the disc edge and the disc core with different metallographic structures and mechanical properties are obtained, the equipment cost is reduced, and the ideal double-performance structure of the turbine disc is realized.
In the scheme of the invention, the disc blank adopts the same alloy and the same powder granularity, and the disc edge are controlled to have unobvious growth of the disc core crystal grains and full growth of the disc edge crystal grains by a method of controlling the disc edge and the disc core temperature gradient in the heat treatment process, so that the different performances of the disc core and the disc edge are finally realized. According to the scheme, the conventional alloy disc heat treatment device is optimized and improved, so that a large temperature gradient can be realized between the disc edge and the disc core during heat treatment, and only corresponding tools are needed to be replaced for discs of different specifications, so that the conventional heat treatment operation is not influenced.
In summary, the alloy disc heat treatment device in the prior art needs custom-made equipment, so that the equipment form is relatively fixed, and only the disc with a fixed shape can be treated; in the face of the scene that the cooling speed is required after the disc is heated, the disc of the device is inconvenient to transport, poor in compatibility and extremely high in running cost. The technical effect of the scheme is that the structural design between the heat insulation tool and the water cooling block is unique, larger temperature gradient can be realized through the upper water cooling block and the lower water cooling block, and an engineer can flexibly replace different heat insulation tools according to the shape of the turbine disc through the structure of clamping the upper heat insulation tool and the lower heat insulation tool of the turbine disc, namely, the disc parts with different specifications can be compatible and the cost is lower.
