Au-Ag-Cu nano-alloys: tailoring of permittivity
Precious metal alloys enables new possibilities to tailor materials for specific optical functions. Here we present a systematic study of the effects of a nanoscale alloying on the permittivity of Au-Ag-Cu metals at 38 different atomic mixing ratios. The permittivity was measured and analyzed numerically by applying the Drude model. X-ray diffraction (XRD) revealed the face centered cubic latti...
متن کاملUsing bond-length-dependent transferable force constants to predict vibrational entropies in Au-Cu, Au-Pd, and Cu-Pd alloys
A model is tested to rapidly evaluate the vibrational properties of alloys with site disorder. It is shown that length-dependent transferable force constants exist and can be used to accurately predict the vibrational entropy of substitutionally ordered and disordered structures in Au-Cu, Au-Pd, and Cu-Pd. For each relevant force constant, a length-dependent function is determined and fitted to...
متن کاملEffect of Minor Au Addition on Glass-Forming Ability and Mechanical Properties of Pd--Cu--Au--Si--P Alloys
The glass-forming ability (GFA), thermal stability and mechanical properties of bulk glassy Pd79Cu6 xAuxSi10P5 (x 1⁄4 0{6 at%) alloys were studied. The results revealed that the minor substitution of Au for Cu strongly affects the thermal stability and GFA of Pd–Cu–Au–Si–P alloys. The alloy in which 2 at% Au was added to substitute Cu (Pd79Cu4Au2Si10P5) exhibits the broadest supercooled liquid ...
متن کاملCorrosion properties of Ag-Au-Cu-Pd system alloys containing indium.
In this study, the corrosion resistance of Ag-Au-Cu-Pd system alloys consisting of 5 or 10 mass% indium was evaluated. Levels of element release and tarnish were determined and electrochemical measurements performed. Results were compared with those for commercial silver-palladium-gold alloy. In terms of electrochemical behavior, the transpassive potential of these experimental alloys was 168-2...
