Liburu elektroniko honi buruz

The formation of metallic glasses and dual-phase composite/hybrid materials is reviewed, as well as the glass transition process and the resulting structural phenomena. These materials exhibit high strength, extreme hardness, good wear resistance and large elastic deformation.

Due to their excellent structural, functional, magnetic, chemical and biological properties metallic glasses are suitable for a great many applications, including in such areas as microelectromechanical devices, pressure sensors, orthopaedic screws and precision surgical instruments.

research activities

Investigation of the formation mechanisms, structure, phase transformations, deformation behavior, mechanical and physical properties of metallic glasses, nanostructured glassy-crystalline/quasicrystalline materials, composite materials having a mixed structure containing nanoparticles embedded in the glassy matrix and high-strength crystalline alloys. Long-term experience in various types of structural analysis techniques, in particular, Transmission Electron Microscopy (TEM) of nanostructured and glassy materials including nanobeam diffraction and high-resolution TEM imaging. X-ray diffraction analysis including creation of the radial distribution functions from Synchrotron-radiation XRD data.

Computer-simulation to materials science (phase transformations, crystallography).

In general, the area of expertise is Physical Metallurgy of metals and alloys which establishes the relationships between the structure of materials and their properties. This subject includes the following topics: solidification, micro- and nano-structure, crystallography, phase transformations, processing, mechanical properties and deformation behavior of metallic materials.
