· JVASP-35720· CrFe2Si

CrFe₂Si is an intermetallic compound combining chromium, iron, and silicon—a hard, brittle material belonging to the family of transition metal silicides. This compound is primarily investigated in research contexts for high-temperature structural applications and wear-resistant coatings, where its thermal stability and hardness could offer advantages over conventional steel alloys, though its brittleness and processing challenges limit current industrial adoption.
