The influence of alloying element S, Se or Te on the oxidation resistance of pure Cu was studied by oxidizing in 0.1 MPa pure oxygen atmosphere at 573-873 K in comparison with a 6N Cu (99.9999 wt.%). The addition of S, Se or Te is found to improve the oxidation resistance of Cu remarkably. This improvement is contributed from the accumulation of alloying element at the Cu2O/Cu interface and seg...

Abstract The use of magnesium alloys in aerospace is relatively restricted by their poor ignition resistance performance. A continuous heating test was conducted to investigate the pure Mg, ZM5, and ZM6 with different alloying elements. It found that elements greatly influenced alloys. With about 2% addition Nd rare earth element, had a higher temperature than Mg. In comparison, which contains ...

This paper reviews the influence of alloying elements Mo, Nb, Ta and Ni on glass formation and corrosion resistance of Cu-based bulk metallic glasses (BMGs). In order to obtain basic knowledge for application to the industry, corrosion resistance of the Cu-Hf-Ti-(Mo, Nb, Ta, Ni) and Cu-Zr-Ag-Al-(Nb) bulk glassy alloy systems in various solutions are reported in this work. Moreover, X-ray photoe...

There is a large interest in using high power lasers for surface alloying or cladding on aluminium alloys, in order to enhance hardness and to improve wear resistance. A partly quasicrystalline surface layer (QC) (Al-Cu-Fe coating) has been obtained by laser cladding on Al-base materials. In addition to crystalline phases (Al5Fe2 and AlisFe4t -with dissolved copper), a quasicrystalline Al-Cu-Fe...

The atomic surface structure of compound semiconductors plays a large role in the growth of semiconductor films and the final microstructure of the film. During growth of InxGa1−xAs films, a mixed-termination surface consisting of a (4x3) reconstruction with common binary InAs or GaAs reconstructions, such as the α2(2x4), has been observed. We have used Density Functional Theory (DFT) to determ...
