· JVASP-93792· CrNi2

CrNi2 is an intermetallic compound in the chromium-nickel system, representing a stoichiometric phase rather than a conventional wrought alloy. This material is primarily of research and specialized industrial interest, employed where specific crystallographic properties or high-temperature phase stability are required, such as in advanced coatings, composite reinforcement phases, or thermal barrier applications. Engineers would select CrNi2 when conventional stainless steels or nickel superalloys cannot meet requirements for phase-specific performance, oxidation resistance at extreme temperatures, or when the material's lattice structure provides advantages in composite or intermetallic-matrix designs.
