摘要：

The possibility of reducing the role of alloy composition in the creation of nanocrystalline structure in Fe-Si-B-based amorphous alloys (with copper, niobium and tantalum additions) by application of flash annealing was studied. Crystallization products were studied using X-ray diffractometry and transmission electron microscopy. It was found that flash annealing remarkably decreases the influence of composition on alloy microstructure after crystallization of the glasses studied. Ultrafine structure with an average grain diameter of less than 25 nm was created in all the iron-based glasses studied in this work. Flash annealing appeared to be a very suitable method for the creation of nanocrystalline materials from metallic glasses. It was revealed that the crystallization product of the first stage of crystallization of Fe73.5Cu1Ta3Si13.5B9 glass depends on the heat treatment method. Primary crystals of alpha-Fe(Si) and Fe3B were observed after conventional and flash annealing
