Formation of the Structure and the Properties of Multicomponent Iron-Based Alloys as a Function of Hydrogenated Melt Solidification Conditions

The influence of the behavior of adsorbed surface-active hydrogen on the phase formation and structuring in multicomponent iron-based systems, namely, steels, cast iron, and FINEMET alloys, is studied. The diffusion activity of elements with adsorbed hydrogen, the hydrogen penetrability, the types of interatomic bonds during the interaction of elements, and their effect on the functional properties of structural products are analyzed. The purpose of this work is to find the character of interatomic bonds of surface-active hydrogen adsorbed on the elements of multicomponent iron alloys and to reveal the influence of hydrogen on the functional and service properties of metal products during their structuring.
