The kinetic Monte Carlo method based on the Multi-States Ising Model,was applied to simulate the effect of microelements on the microstructural evolution of Al-Ag alloys during initial aging stage.

Taking into account the influence on the lattice constant from temperature,the valence electronic structures of GP zones of η-form in the Al-Ag alloy,and the interfacial energy between GP zones of η-form and matrix were calculated by using empirical electron theory in solid and molecules(EET) and the extension of Becker model.

The valence electron structure of GP zone ? phase in Al-Ag alloy was calculated according to the “empirical electronic theory in solid”(EET), and the interface energy based on the information of the valence electron structure was calculated also.

Strain strengthening of Cu-Ag alloy in situ filamentary composites;

Effects of annealing and cold-working on properties of continually-unidirectionally solidified Cu-Ag alloy;

The Cu-Ag alloy in situ filamentary composites with different Ag contents were prepared.

Oxidation of Ag-Cr alloys prepared by powder metallurgy in 0.1 MPa O_2;

This scale structure is different from the mixed oxide structure of the Ag-Cr alloy with coarse grain sizes prepared by powder metallurgy, which is attributed to the large decrease in the alloy grain size, the rapid dissolution of the Cr-rich.
