An investigation was conducted to explore the applicability of eddy current and microwave techniques to characterize grains size variation during mechanical alloying. A series of Nanocrystalline (Fe65Co35)70Al30 samples have been prepared, these structures are prepared using mechanical alloying based on planetary ball mill under several milling conditions. Mechanical alloying is a non-equilibri...

The alloying behaviour of materials is a well-known problem in all kinds of compounds. Revealing the heteroatomic distributions in two-dimensional crystals is particularly critical for their practical use as nano-devices. Here we obtain statistics of the homo- and heteroatomic coordinates in single-layered Mo(1-x)W(x)S(2) from the atomically resolved scanning transmission electron microscope im...

The effect of different alloying conditions (alloying temperature, annealing period) on the electrocatalytic activities for the oxygen reduction reaction (ORR) by three carbon-supported Pt alloy electrocatalysts (WCr, WCo, m i ) was investigated and correlated with electronic and structural parameters determined by in-situ XAS. The results indicate that all the Pt alloys show enhanced ORR activ...

the chemical composition and uniform distribution of alloying elements in the matrix of austempered ductile irons (adis) have significant influences on their properties, e.g. segregation of the alloying elements have detrimental effects on the mechanical properties of these materials. unlike previous studies, the homogenization treatment via partial melting was used in this study in order to re...

The electromigration wind force in various Al alloys is calculated using a Green’s-function method for the calculation of the electronic structure. The influence of the environment of the jumping atoms is studied in detail in the Al-Cu alloy. Alloys of Al with 3d and 4sp alloying elements are studied systematically in order to investigate the relation between the electronic states of the alloyi...
