Experiments were carried out at 1323 to 1773K which involved the equilibration of the surface of Fe plates against liquid Ag-Cu alloys. The materials used were all of at least 3N-purity. The equilibrated Fe plates were essentially binary alloys since no Ag was found in them. Interdiffusion coefficients (table 6) were deduced from the penetration profiles of Cu in the plates.
