Different methods for production of alloys in the amorphous and nanocrystalline states are considered. It is shown that the main advantage of amorphous brazing filler alloys is that they are produced in the form of thin ductile foils, which can be used as inserted elements of any shape to fabricate unique structures, primarily for aerospace and nuclear power engineering. High chemical homogeneity of amorphous brazing alloys and their narrow melting point ranges provide good wetting of the surface treated, and reduction of the probability of formation of lacks of penetration and brittle phases, thus ensuring high strength of the brazed joints.
