Inconel 738 Lc Turbine Blade

Inconel 738LC is a superalloy commonly used in the manufacture of turbine blades for high temperature applications. It is a nickel-based alloy with excellent high temperature strength, hot corrosion resistance and oxidation resistance.

Inconel 738LC superalloy turbine blades are usually manufactured by investment casting (Investment Casting), the specific steps are as follows:

Mold preparation: Use high temperature resistant ceramic materials to make the mold of the blade. This mold is usually made of refractory material and has the exact geometry of the blade and internal cooling channel structure.

Melting alloy: Melting Inconel 738LC superalloy material, usually using electric arc furnace or vacuum melting furnace. During the melting process, the appropriate amount of alloying elements and other adjustment components are added to obtain the desired high temperature properties.

Injection Mold: Inject molten Inconel 738LC alloy into a pre-prepared ceramic mold. The injection process requires precise control of temperature, pressure and injection speed to ensure that the entire mold is filled and the details and internal structure of the blade are formed.

Solidification and Cooling: Wait for the molten alloy to solidify and cool in the mold for it to achieve sufficient strength.

Mold removal: Once the alloy has solidified and cooled, the mold can be broken or dissolved to remove the blade from the mould.

Trimming and post-processing: As-cast blades are trimmed to remove any excess material or defects and carry out necessary heat treatment, surface treatment and inspection to meet design requirements.
