Ni3Allike
Ni3Allike is a term used in materials science to describe a family of nickel-rich intermetallic compounds that resemble the nickel aluminide Ni3Al in crystal structure and composition trends. It denotes compounds with approximately Ni3Al-type stoichiometry, often with substitutions on Ni or Al by small amounts of other elements to tailor properties. The term is typically used in theoretical or design contexts and does not refer to a single, universally defined phase, but to related materials with similar ordering and structure.
Crystal structure and composition: Most Ni3Allike materials are described as adopting an ordered L12 (face-centered cubic)
Synthesis and processing: Ni3Allike alloys are usually produced by traditional metallurgy routes such as arc melting
Properties and behavior: These alloys typically exhibit high melting points, good creep resistance, and notable oxidation
Applications and outlook: Potential applications include high-temperature structural components in aerospace and energy sectors, as well
