Material Characteristics
The nickel-based Alloy 718 is suitable for the use at high temperatures and under corrosive
conditions. The superalloy is frequently used for compressor and turbine blades, for example in
gas turbines or in the aerospace industry. Additive manufacturing with downstream heat treatment processes enable good
modification possibilities of the materials properties, which leads to a broad range of possible applications.
| Properties | Unit | As built 1) | Heat-treated 2) | |
|---|---|---|---|---|
| Tensile Strength Rm | Mpa | 1050 ±30 | 1500 ±30 | |
| Yield Strength Rp0,2 | MPa | 740 ±20 | 1350 ±20 | |
| Elongation at Break A5 | % | 28 ±3 | 10 ±3 | |
| Young‘s Modulus E | GPa | 185 ±10 | 215 ±15 | |
| Charpy Notch Toughness Av | J | 75 ±5 | 25 ±3 | |
| Hardness | HV | 305 ±5 | 470 ±5 |
- The specified material properties were determined at room temperature. They are multidimensionally dependent on many different machine and process parameters. Without further investigation, the material properties do not constitute a sufficient basis for component dimensioning.
- Specific heat treatment processes lead to optimized mechanical-technological properties to meet the component requirements.
