Single Crystal Casting Segment

The Single Crystal Cast Turbine Segment is one of the key components in turbomachinery and is manufactured using a single crystal casting process. Single crystal casting is an advanced metal forming process that solidifies metal in a ceramic mold with a single grain to give the turbine segment a single grain structure without grain boundaries, thereby providing excellent high temperature strength and durability.

Directional Casting Turbine Segment

Features of Single Crystal Cast Turbine Segment

Single crystal structure

It has a single grain structure without grain boundaries, providing excellent high temperature strength and thermal corrosion resistance.

Directional solidification

The grains grow in a single direction, so that the turbine segment has consistent material properties in a specific direction.

High temperature performance

It has excellent high temperature oxidation resistance and thermal corrosion resistance, and is suitable for high temperature working environments.

Complex geometry

It can produce complex geometries and fine structures to meet the design requirements of turbomachinery for blades.

Application areas of single crystal cast turbine segments

  1. Aerospace: Used for turbine blades of aircraft engines to provide power output under high temperature and high pressure.
  2. Power generation industry: Used for turbine blades in gas turbines and steam turbines to provide power conversion.
  3. Industrial application: used in industrial turbines, compressors, pumps and other equipment to provide high-temperature, high-pressure liquid or gas compression and transportation.

Manufacturing process and quality control

  1. Mold design: design precision ceramic molds to ensure that the shape and size of the turbine section meet the design requirements.
  2. Material selection: select suitable single crystal alloy materials to ensure that the turbine section has excellent high-temperature performance.
  3. Process control: strictly control the parameters such as temperature, pressure and speed of the casting process to ensure the forming quality and consistency of the turbine section.
  4. Non-destructive testing: use non-destructive testing methods such as ultrasonic testing, X-ray testing and magnetic particle testing to ensure that there are no defects inside the turbine section and meet the quality requirements.
