2. Chemical Composition of Inconel 713C
The strength and reliability of Inconel 713C come from its carefully balanced chemistry. The alloy is reinforced with gamma prime (γ′) Ni₃(Al,Ti) precipitates and grain boundary carbides.
| Element | Typical wt.% | Function |
|---|---|---|
| Nickel (Ni) | Balance | Matrix element, provides toughness |
| Chromium (Cr) | 12.5 | Oxidation and corrosion resistance |
| Molybdenum (Mo) | 4.5 | Solid solution strengthening |
| Niobium (Nb) | 2.0 | Carbide formation, creep resistance |
| Aluminum (Al) | 6.0 | Gamma prime strengthening |
| Titanium (Ti) | 0.6 | Gamma prime formation |
| Carbon (C) | 0.12 | Carbide reinforcement |
| Zirconium (Zr) | 0.1 | Grain boundary ductility |
| Boron (B) | 0.01 | Grain boundary strengthening |
This composition enables a balance of high temperature strength and oxidation stability that makes Inconel 713C ideal for hot section components.
3. Mechanical Properties of Inconel 713C
The following are typical mechanical properties of Inconel 713C at room and elevated temperatures.
| Property | Value |
|---|---|
| Density | 8.0 g/cm³ |
| Melting Range | 1260–1335 °C |
| Tensile Strength at 20 °C | 900–1050 MPa |
| Yield Strength at 20 °C | 700–800 MPa |
| Elongation at 20 °C | 2–4 percent |
| Hardness | 340–370 HB |
| Tensile Strength at 870 °C | ~600 MPa |
| Creep Rupture Strength at 870 °C 100h | Excellent |
These values confirm its capability to perform under high loads and cyclic stresses.
4. High Temperature Performance
One of the main reasons Inconel 713C remains widely used is its proven performance in environments up to 950 °C.
Key factors include:
Creep resistance under prolonged stress at elevated temperatures.
Fatigue resistance under cyclic loading typical of rotating turbine parts.
Oxidation resistance from chromium and aluminum oxide surface scales.
Carbide reinforcement that strengthens grain boundaries against crack propagation.
This makes it particularly suitable for turbine blades, vanes, and turbocharger wheels where mechanical and thermal stresses are extreme.
