· JVASP-4708· B2Au

B2Au is an intermetallic compound with a B2 (CsCl-type) crystal structure, composed of gold and another element in a 1:1 atomic ratio. This material belongs to the family of ordered intermetallics, which are candidates for high-temperature and structural applications due to their ordered atomic arrangement and potential for enhanced mechanical properties. B2Au remains primarily a research material; its development targets applications requiring the combination of gold's chemical stability with intermetallic hardness and stiffness, though practical engineering use is limited by cost and processing challenges inherent to gold-based compounds.
