40 cu au phase diagram

AuCu is Tetraauricupride structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Au1- is bonded in a distorted body-centered cubic geometry to eight equivalent Cu1+ atoms. All Au-Cu bond lengths are 2.73 Å. Cu1+ is bonded in a body-centered cubic geometry to eight equivalent Au1- atoms. From the two-phase sequence rule, there is a two-phase region separating δ and δ ′ on the left along horizontal temperature traverses (isotherms), similar to the phase diagram of Au-Cu [92, 95 ...
