OBTAINING AND MECHANISM OF FORMATION OF THE HEXAGONAL PHASE OF ε-IRON FOR THE DESIGN ALLOY OF Fe-Ni

The high-frequency alternating current (HFC) method was used to cover the Fe-Ni alloy from aqueous solutions of salts under normal conditions (P = 0.1 MPa, T = 298 K) containing a stable hexagonal close-packed phase (hcp) of ε-Fe. The mechanism of formation of this phase is justified. The exotic phase of epsilon-iron has a high density (10.5 g / cm3), microhardness and corrosion resistance. These properties are important when creating structural materials
