X-ray diffraction analysis including creation of the radial distribution functions from Synchrotron-radiation XRD data. 

Major Scientific Advances

·        Rejuvenation mechanism of metallic glasses by non-affine thermal strain during cryogenic treatment.

·        Investigation of bulk metallic glassy surface_ native oxides: their atomic structure, growth rate and electrical properties.

·        A new class of materials: nanostructured Au-, Pd-, Ti- and Zr-based metallic glasses for chemical and biological applications.

·        Various works on the analysis and improvement of glass-forming ability of metallic glasses. Separation of intrinsic and extrinsic factors influencing the glass-forming ability of alloys.

·        Multiple works on the crystallization mechanisms of metallic glasses.

·        Relation between the atomic structure of metallic glass-forming liquid and its fragility (temperature dependence of viscosity) by in-situ cooling under synchrotron radiation. Structural basis for supercooled liquid fragility is established by synchrotron-radiation method and computer simulation.

·        Atomic structure of metallic glasses studied by high-resolution transmission electron microscopy and synchrotron radiation X-ray diffractometry.
