NC15TNBA superalloy has excellent high-temperature properties, mainly due to its complex chemical composition and crystal structure. The alloy is mainly composed of elements such as nickel (Ni), chromium (Cr), aluminum (Al), tantalum (Ta), to which an appropriate amount of niobium (Nb) is added. The reasonable ratio of these elements and the special crystal structure make the NC15TNBA alloy have a high melting point and good mechanical properties, allowing it to withstand extreme conditions in a high-temperature environment.
Process functions and requirements.
1. The casting temperature of the alloy is between 1220 and 950, and it is easy to form. The alloy is solution treated after an intense forming process.
2. The average scale of grain size of the alloy is closely related to the deformation degree of the forging and the final forging temperature.
3. The alloy has a good welding function and can be welded in various ways. Aging after welding gives a strength that approximates that of a fully heat-treated situation.
4. The heat treatment of parts is carried out in a neutral or restorative atmosphere without sulfur to avoid vulcanization.
In summary, NC15TNBA superalloy, as a new type of superalloy material, has excellent high-temperature strength, oxidation resistance and thermal creep properties, and has a wide range of application prospects in aerospace, energy and chemical industries. Its composition, physical properties, process application and future development direction and other characteristics show its great potential in high-temperature environment, and it is believed that there will be more breakthroughs and application value discoveries in the near future.
