First principles study on structural, electronic and elastic properties of AgX and AuX (XÂ =Â Mg, Sc, Zn and Cd) intermetallic compounds

► The DFT calculations have been performed for eight B2 - type intermetallic compounds. ► Hybridization between bands presented by partial band structure for AgZn and AuZn. ► Calculated elastic moduli obey traditional mechanical stability of cubic condition. ► The AuZn is most ductile amongst the AgX and AuX compounds.
