| Description
| - Částečně zkrystalizované slitiny Fe91-yMo8Cu1By patří do skupiny slitin typu NANOPERM, které mají vynikající magnetické vlastnosti. Molybden, jako legující prvek, způsobuje snížení Currieovy teploty slitin až k pokojové teplotě, a to jak ve stavu relaxovaném, tak ve stavu částečně zkrystalizovaném. To otevírá možnosti pro technické aplikace. Tato práce se zabývá studiem strukturních přeměn ve třech vybraných slitinách (y = 12, 15, 17) po různých tepelných zpracováních metodami TEM, XRD a DSC. Jsou také změřeny difúzní charakteristiky obou hlavních kovových komponent (Fe, Mo) v intervalu teplot 548 – 773 K. Bylo zjištěno, že rychlost objemové difúze Fe a Mo v relaxovaném stavu je přibližně stejná, ale difuzivita Fe po hranicích zrn je výrazně vyšší, než difuzivita Mo. Tento výrazný rozdíl difuzivitě po hranicích zrn může působit jako faktor zlepšující strukturní stabilitu zkoumaných slitin. (cs)
- Partly crystallized alloys Fe91-yMo8Cu1By belong to a NANOPERM-type family with excellent soft-magnetic behavior. Molybdenum, as an alloying element, causes that the Currie temperature of both amorphous and nano-crystallized form of the alloys is close to the room temperature, which opens possibilities to numerous applications. In the present work, structure changes of three chosen alloys (y = 12, 15, 17) are investigated after several temperature treatments by TEM, XRD and DSC and diffusivity of the principal metallic components is measured in the temperature interval 548 – 773 K. It was found that bulk diffusion coefficients of Fe and Mo in relaxed amorphous state are about the same, but grain boundary diffusivity of Fe is much higher than that of Mo. Such a difference in grain boundary diffusivity may act as structure stabilizing factor.
