Diffusion in Gold-rich Gold-Aluminium Alloys

Electronic structure of copper-rich copper-gold alloys.

We present and discuss angle-resolved photoemission measurements from the (111) and (100) faces of CuAu single crystals containing 10 at. %%u oA u in th ebul k, togethe rwit hcomputation sof complex-energy bands and densities of states in the Cu90Aulo random alloy. Our calculations permit (.' a good understanding of the shifts and smearings in t e spectrum of Cu arising from the addition of Au ...

The aluminium - copper - gold ternary system

Despite Au, Al and Cu being individually very wellknown elements, their ternary phase diagram has not been studied in as much detail as those of many other Au-containing ternaries. Here we review what is known, and consider the prospects for technological exploitation of some of the ternary compositions. The components of greatest interest in Al-Au-Cu may be the β-phases, at least two of which ...

Characterization of 14 Karat Gold Alloys

This paper is a continuation of the project we presented at the 2010 Santa Fe Symposium® in which we defined a characterization system and analysis of data on 18K gold alloys. The research carried out since then has enabled us to connect the physical-mechanical characteristics of each alloy with its chemical composition, thereby identifying the best solution possible to produce a specific item....
