Nickel Alloy ZhS32
General Technical Characteristics
ZhS32 is a heat-resistant cast nickel-based alloy designed for manufacturing critical gas turbine engine components operating under high temperatures and significant mechanical loads. The alloy contains rhenium, which improves its high-temperature strength and resistance to long-term creep.
The material belongs to the group of modern highly alloyed heat-resistant superalloys. It is used to manufacture turbine rotor blades, including components with a single-crystal structure that provides enhanced operational reliability.
ZhS32-VI is a separate alloy modification developed for producing single-crystal cast components. Its composition and properties should be considered separately from those of the base ZhS32 grade.
Chemical Composition
Approximate chemical composition of ZhS32, wt.%:
| Element | Content, % |
|---|---|
| Nickel (Ni) | Balance |
| Chromium (Cr) | 4.3–5.6 |
| Cobalt (Co) | 8.0–10.0 |
| Tungsten (W) | 7.7–9.5 |
| Aluminium (Al) | 5.6–6.3 |
| Rhenium (Re) | 3.5–4.5 |
| Tantalum (Ta) | 3.5–4.5 |
| Niobium (Nb) | 1.4–1.8 |
| Carbon (C) | 0.12–0.18 |
| Molybdenum (Mo) | 0.8–1.4 |
| Boron (B) | approx. 0.02 |
| Cerium (Ce) | approx. 0.025 |
The composition is based on published reference data for ZhS32. The ZhS32-VI modification is subject to separate technical requirements. For example, its Cr content is 4.5–5.3%, Co is 9.0–9.5%, W is 8.1–8.9%, and Re is 3.6–4.3%. The exact composition must be verified against the applicable technical specifications and the material certificate for the specific batch.
Mechanical and Operating Properties
ZhS32 is characterized by the following properties:
- High-temperature strength during prolonged exposure to elevated temperatures.
- Resistance to creep and deformation under mechanical loads.
- Structural stability during high-temperature operation.
- High strength due to γ′-phase precipitation strengthening.
- Suitability for producing single-crystal cast components.
The presence of rhenium, tungsten, and tantalum contributes to increased strength and resistance to high-temperature deformation. Actual operating performance depends on the casting structure, casting technology, and heat treatment conditions.
Applications
Nickel alloy ZhS32 is used in the manufacture of:
- Gas turbine engine rotor blades.
- Single-crystal aircraft turbine blades.
- Hot-section components of gas turbine units.
- Critical cast components for aircraft engines.
- Power turbine components operating at elevated temperatures.
Features of Nickel Alloy ZhS32
The main feature of ZhS32 is its rhenium content, which improves creep resistance and helps maintain strength during prolonged high-temperature operation. Tungsten and tantalum strengthen the material, aluminium contributes to the formation of the strengthening γ′ phase, and cobalt helps stabilize the structure.
The alloy is particularly востребован in the production of single-crystal turbine blades, where high-temperature strength, reliability, and long service life are essential.
