NiCr-based oxide dispersion-strengthened (ODS) alloys are engineered for outstanding high-temperature performance. Reinforced with ultra-fine Y₂O₃ nanoparticles, these alloys combine excellent mechanical strength with exceptional resistance to oxidation and thermal fatigue.
The NiCr variants offer:
- Superior creep and tensile strength up to 1200 °C
- Excellent resistance to hot gas corrosion and liquid glass
- Outstanding fatigue resistance even at extreme temperatures
- High hardness and structural stability through coarse grain recrystallization
- Nominal composition: Ni (balance), 20% Cr, ~0.6% Y₂O₃
Thanks to its robust thermal and chemical stability, the NiCr ODS can be used in:
- Aerospace and space propulsion components
- Glass processing equipment
- High-temperature test rigs
These ODS alloys are manufactured via powder metallurgy method using high-energy mechanical alloying, ensuring homogeneous distribution of strengthening particles and a highly stable microstructure and hot isostaic pressing (HIP) followed by extrusion or rolling to realize long or flat products
