The evolution of composition and structure at metal-metal interfaces: Measurements and simulations,n is drawn to similarities and differences arising from the substrate orientation. The tendency for Ti to grow as an overlayer while the other metals form interface alloys is discussed. Monte Carlo computer simulations using EAM potentials are presented for Ni on the three orientations of A1.
