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 specialty 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 sulfur, 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 1450-1550°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 vaporization. Continuous stirring ensures uniform distribution of cerium within the molten nickel. After homogenization, the alloy is cast into ingots or granulated for downstream use. Rapid cooling or solidification may be employed to minimize segregation and promote uniform microstructure.
