The dependence of phase formation and mechanical properties on the chemical composition has been investigated for Pt-Ir and Pt-Au combinatorial thin films. The formation of a single, metastable Pt-Ir solid solution has been observed for all experimental compositions and temperatures. Upon Ir addition to Pt the experimentally determined changes in lattice parameter and Young’s modulus display rule of mixture behavior which is in good agreement with our ab initio data. Whereas, in the Pt-Au… 
Kinetically Limited Phase Formation of Pt-Ir Based Compositionally Complex Thin Films
The phase formation of PtIrCuAuX (X = Ag, Pd) compositionally complex thin films is investigated to critically appraise the criteria employed to predict the formation of high entropy alloys. The
Role of Thermodynamics and Kinetics in the Composition of Ternary III-V Nanowires
The model derived describes the evolution of the solid composition from the nucleated-limited composition to the kinetic one and contains the miscibility gap at relevant temperatures for growth of InxGa1−xAs NWs, which may be suppressed completely in the steady-state growth regime at high supersaturation.
Defects in an orthorhombic MoAlB MAB phase thin film grown at moderate synthesis temperature.
Here, we report on atomic scale characterization of various defects in a MoAlB (MAB) phase thin film grown by DC sputtering at a synthesis temperature of 700 °C. Aberration-corrected scanning
Hybrid magnetron sputtering of ceramic superlattices for application in a next generation of combustion engines
A hybrid magnetron sputtering process (dcMS/HiPIMS) was developed to manufacture nanostructured CrN/Cr 1-x Al x N multilayers, motivated by improving the low-emission efficiency when applied on


Modeling of metastable phase formation diagrams for sputtered thin films
A method to model the metastable phase formation in the Cu–W system based on the critical surface diffusion distance has been developed and the correlative experimental and theoretical research strategy adopted enables it to efficiently describe the relationship between the solubilities and the critical diffusion distances.
Combinatorial Study of Gradient Ag-Al Thin Films: Microstructure, Phase Formation, Mechanical and Electrical Properties.
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 and suggests that a hcp Ag- Al alloy can have a potential use in sliding electrical contact applications and in the future will replace pure Ag in specific electromechanical applications.
Experimental Study of Au-Pt-Sn Phase Equilibria and Thermodynamic Assessment of the Au-Pt and Au-Pt-Sn Systems
The Calphad method has been employed to generate a consistent thermodynamic description of the Au-Pt-Sn system, including a thermodynamic evaluation of the Au-Pt system, incorporating all phase
Platinum-Iridium Alloys as Oxygen Reduction Electrocatalysts for Polymer Electrolyte Fuel Cells
Platinum-iridium (Pt-Ir) alloy electrocatalysts for polymer electrolyte fuel cell (PEFC) cathodes were prepared, and their physical and electrochemical properties were examined. A variety of
Mechanical properties of Pt-Ir and Ni-Ir binary alloys for glass-molding dies coating.
The surface roughnesses of all specimens annealed at 700 degrees C were slightly larger than as-deposited coatings and the value of reduced modulus of this specimen coating is the lowest and the corrsponding Ra value is the largest compared with the rest of Ir-based coatings in the oxidation testing.
High-Temperature Mechanical Properties of the Platinum Group Metals
Due to their excellent chemical stability, oxidation resistance, and resistance to the action of many molten oxides, the platinum group metals (pgms): iridium, platinum and rhodium are widely used
