NC6641 Nickel-Cerium Master Alloy (Ni-Ce Alloy)

Nickel-Cerium Master Alloy (Ni-Ce Alloy) Description

Nickel-Cerium Master Alloy is commonly used in the aerospace, automotive, and chemical industries due to its exceptional ability to enhance the performance of various alloys. The addition of cerium to nickel helps improve the alloy's oxidation resistance, making it ideal for high-temperature environments and applications where durability and performance are critical.

This master alloy is typically used as a deoxidising agent in the production of stainless steels, superalloys, and other specialised alloys. It also finds applications in the creation of components for gas turbines, engine parts, and high-performance tools, where excellent thermal stability and resistance to corrosion are necessary.

Nickel-Cerium Master Alloy (Ni-Ce Alloy) FAQs

Q1. What are the main applications of Ni-Ce Alloy?

It is used in superalloys, stainless steels, and speciality alloys for aerospace, energy, and high-temperature industrial components, where cerium enhances creep resistance and reduces oxidation or sulfidation.

Q2. How does cerium improve alloy performance?

Cerium acts as a scavenger for oxygen and sulphur, refines grain boundaries, and promotes stable oxide formation, which improves corrosion resistance and mechanical stability at elevated temperatures.

Q3. How is Ni-Ce master alloy added to alloy systems?

It is typically added to the melt during alloy production or secondary refining stages, ensuring good mixing and complete dissolution under proper thermal and atmospheric conditions.

1.       Common Preparation Methods

Nickel-Cerium Master Alloy is produced through vacuum induction melting or argon-protected melting processes. High-purity nickel is first melted in a graphite or ceramic crucible under an inert gas atmosphere to prevent oxidation. Once the nickel is fully molten (typically at temperatures around 1 450-1 550°C), cerium metal is slowly added in a controlled manner. Due to cerium’s high reactivity and lower melting point (~798°C), it must be introduced carefully to avoid oxidation and excessive vaporisation. Continuous stirring ensures uniform distribution of cerium within the molten nickel. After homogenisation, the alloy is cast into ingots or granulated for downstream use. Rapid cooling or solidification may be employed to minimise segregation and promote uniform microstructure.
