| The ``generic embedded atom model (GEAM) has been investigated^M recently [Phys. Rev. E {\bf 69}, 021509 (2004)] to analyze the^M qualitative equilibrium and nonequilibrium properties of bulk^M metals in both undeformed and shear deformed states. In the^M present work, a natural extension of the GEAM is proposed and^M applied to characterize the microscopic structure, dynamics and^M wear at clean commensurate metal$_A$-metal$_A$ and^M metal$_A$-metal$_B$ sliding interfaces. Non-equilibrium molecular^M dynamics simulation, used as a GEAM solver, reveals that the^M dynamics of dislocations, crystalline domains, and related flow^M behaviors (stress tensor, shear moduli) are coupled. The rotation^M of crystal domains is detected to trigger material mixing at the^M interface in early stages of sliding. Further, we study the^M dependence of structural changes in inhomogeneous metal interfaces^M on the relevant model parameters. A relation is established^M between shear moduli, effective shear rate and shear stress across^M the interface.
