We demonstrate the influence of interfacial strain on the growth modes of Ag films on Al(111), despite the small magnitude of the lattice misfit in this system. The strain is relieved by the formation of stacking fault domains bounded by Shockley partial dislocations. The growth mode and the step roughness appear to be strongly connected. Growth is three-dimensional (3D) as long as the steps ar...

In this study, a wide range of combined ageing treatments and cold work deformations in the Al 4.2 wt% Ag alloy matrix were proposed, aiming to investigate the effect of defects such as precipitates (Ag2Al plates) and dislocations on the mechanical and electrochemical behavior of Al–4.2 wt% Ag alloys. Further reductions of thickness from 10 to 60%, decreases the mean size of Ag2...

Motivated by the studies done by G. Siromoney et al. (1973) and Alexandru Mateescu et al. (1998) we examine the language theoretic results related to shuffle on trajectories by making use of Siromoney array grammars such as (R : R)AG, (R : CF )AG, (CF : R)AG, (CF : CF )AG, (CS : R)AG, (CS : CS)AG and (CF : CS)AG which are more powerful than the Siromoney matrix grammars (1972) and are used to m...

A combinatorial approach is applied to rapidly deposit and screen Ag-Al thin films to evaluate the mechanical, tribological, and electrical properties as a function of chemical composition. Ag-Al thin films with large continuous composition gradients (6-60 atom % Al) were deposited by a custom-designed combinatorial magnetron sputtering system. X-ray diffraction (XRD), energy dispersive X-ray s...
