Description

Technical Field

[0001] The present invention relates to the technical field of superalloy testing equipment, and particularly to a diffusion and performance testing system for superalloy materials. Background Art

[0002] Superalloy materials are mainly used in the manufacture of key components in high-temperature and high-pressure environments such as aerospace and gas turbines. Due to their excellent oxidation resistance, corrosion resistance, and mechanical properties, superalloy materials maintain a stable organizational structure under high-temperature conditions and are widely used in fields such as aeroengine turbine blades, turbine disks, and gas turbines. For superalloys, mechanical properties and thermal diffusivity are important indicators for evaluating their performance.

[0003] In aeroengines and gas turbines, superalloy materials need to work under extreme high temperatures for a long time. A decrease in thermal diffusivity may lead to risks such as local overheating and stress concentration. Therefore, when designing and using high-temperature components made of superalloy materials, it is necessary to consider the change in their thermal diffusivity to ensure stable operation under extreme working conditions. Therefore, those skilled in the art hereby propose a solution for a diffusion and performance testing system for superalloy materials. Summary of the Invention

While the inner connecting rods 36 approach each other, drive the outer connecting rods 34 to approach each other, and then the inner surfaces of the clamping jaws 35 gather together to clamp the surface of the alloy material.

[0044] Since a balanced and stable magnetic field is formed after multiple coils in the Helmholtz coil 23 are energized, and the alloy material passes through the inside of the electromagnetic heating coil 22 and the Helmholtz coil 23, the electromagnetic heating coil 22 is used to heat-treat the alloy material, so that a local area of the alloy material is heated to a high-temperature environment. At this time, the brake of the right servo motor 31 is released, and the servo drive motor 15 is used to drive the transmission shaft 16 to rotate, so that one end of the alloy material rotates and the other end remains stationary.
