Anotace
The topic of proposed project is to deepen the assessment of interplay between structure and properties of nano-powders prepared by ball milling and mechanical alloying. The original approach will be based on systematic investigations of the structure of nano-grain boundaries and cores. The main attention will be devoted to formation of defects in grain surfaces and to influence of various gases (O2, N2, H2, Ar) and/or milling components on the structure of boundaries and cores of nanograins in a close relation to the properties of final iron-based materials. The combination of microstructure-sensitive Mössbauer spectroscopy and defect-sensitive positron annihilation spectroscopy supported by other experimental methods, e.g. TEM, HREM, (HR)SEM, XRD, DSC, and magnetic measurements guarantees to obtain novel and valuable information. The subsequent annealing and monitoring the changes of structural and physical properties will contribute to extension of the obtained results and to prediction of modifications of the prepared materials aimed at optimization of their magnetic behavior.
