Non-Metallic Elements Dissolved in Molten Alloy Steels

Study of Non - Metallic Inclusions in Alloy 825 Hans

Gamma ray decomposition of dissolved organic substances in river water without compositional change of metallic elements.

A river water sample was irradiated with 60Co gamma-rays under aerobic conditions, and the changes of the organic substances in the sample were examined by the analyses of the dissolved organic carbon (DOC), organic composition, UV spectrum and molecular-weight distribution. By the irradiation, the DOC decreased with irradiation dose following the first-order kinetics. In addition, the changes ...

Recent developments in the coordination chemistry of porphyrin complexes containing non-metallic and semi- metallic elements

The tremendous potential for the manifold applications of porphyrins, porphyrazines, and phthalocyanines derives from their photophysical and electrochemical properties, their remarkable stability, and their predictable and rigid structure. These applications include nonlinear optics, catalysts, sensors, actuators, molecular sieves, and therapeutics. All of these properties are modulated by app...

Modelling Simultaneous Alloy Carbide Sequence in Power Plant Steels

ε-carbide in Alloy Steels: First-principles Assessment

There is now a large volume of sophisticated steels which rely on silicon as an alloying addition with the purpose of avoiding the precipitation of cementite. But there is also evidence that the silicon can enhance the formation of ε–carbide; the mechanism of this effect is not understood and the absence of appropriate thermodynamic data makes it impossible to conduct calculations. We report he...
