The PhD thesis is focused on the employment of unconventional techniques of thermal processing in order to tailor the structural and magnetic properties of nanocrystalline alloys based on 3-d metals. We plan to use facility for ultra-rapid annealing of thin metallic ribbons constructed recently at IEP SAS. In this facility, the annealed samples are clamped between pair of the pre-heated massive Cu-blocks and typical annealing times take few seconds. High heating rates and much shorter processing times as compared to conventional annealing allow extend the composition interval where the annealed samples are still capable to form nanocrystalline structure. The other technique of thermal processing in this work is the annealing in a presence of high magnetic fields. We plan to perform a detailed study of structural and magnetic properties of selected alloy systems. The main goal of thesis is improvement of functional properties of studied materials for potential technical applications.
