【 摘 要 】

The literature data on the problem of modification of the structure and properties of the Fe-based rapid-quenched alloys by various methods of severe plastic deformation (SPD) are reviewed. The SPD methods such as Bridgman cell torsion, ball-mill processing and high-frequency shock treatment as well as their advantages and disadvantages are considered. By examples of a large number of amorphous Fe-based alloys, the influence on their structure and properties of each of the considered SPD methods is analysed. Based on the obtained data, the mechanism of deformation nanocrystallization of amorphous alloys is proposed.
