The Influence of Internal Stress on the Nanocrystal Formation of Amorphous Fe73.8Si13B9.1Cu1Nb3.1 Microwires and Ribbons

The early stages of nanocrystallization in amorphous Fe73.8Si13B9.1Cu1Nb3.1 ribbons and microwires were compared terms their internal stress effects. microstructure was investigated by the X-ray diffraction method. Classical expressions crystal nucleation growth modified for while accounting distribution, order to justify XRD data. It assumed that, due strong compressive stresses on surface part tensile central part, crystallization microwire proceeded faster than part. results revealed more rapid that ribbons. During initial period annealing, a caused formation predominantly crystallized layer. obtained open up new possibilities varying high-frequency properties application modern sensorics.
