Nuclear & Extreme Environment Materials

WCrY is an advanced tungsten-based refractory alloy engineered for Hot Isostatic Pressing (HIP) consolidation, followed by high-temperature annealing above 1500 °C to eliminate Cr-rich secondary phases and stabilize a single-phase bcc structure. This thermal treatment process is essential for achieving thermal shock resistance and mechanical integrity under extreme operational conditions.

Designed to withstand steady-state and transient heat loads in the MW/m² range, WCrY alloy is ideal for plasma-facing components such as divertor and first wall assemblies in fusion reactor environments. The strategic addition of chromium and yttrium enhances high-temperature oxidation resistance up to 1000 °C and promotes grain refinement through in-situ oxide dispersion strengthening (ODS).

With its exceptional combination of thermal stability, radiation resistance, oxidation protection, and mechanical performance at elevated temperatures, WCrY represents a leading material solution for next-generation fusion energy systems and other extreme environment applications.

Eurofer97-ODS is an oxide dispersion-strengthened (ODS) ferritic-martensitic steel powder, developed by MBN Nanomaterialia using its proprietary Mechanomade® process. Alloyed from elemental precursors with nano-scale Yttrium Oxide (Y₂O₃), it is designed for high-temperature, high-radiation environments such as fusion reactors and advanced energy systems.

The uniform oxide dispersion enhances creep resistance, microstructural stability, and radiation tolerance. With tight particle size control, the powder ensures excellent flowability and packing density for advanced consolidation techniques.
Eurofer97-ODS is compatible with HIP, Spark Plasma Sintering (SPS), and extrusion, enabling the production of dense, near-net-shape components with reduced material waste.

Key Benefits:
◉ High thermal and radiation stability
◉ Grain growth resistance
◉ Cobalt- and nickel-free
◉ Suited for net-shape consolidation

Applications include first-wall structures, thermal shields, and heat exchangers in demanding nuclear environments.
