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 deoxidizing agent in the production of stainless steels, superalloys, and
other specialized 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 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.

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.
