N2 - The structure of hypoeutectic, hypereutectic, and eutectic Ti-Fe in the alloys produced shape of arc-melted ingots was found to consist of the ordered Pm-3m TiFe and disordered BCC Im3̄m β-Ti solid solution phase. The dimensions of the ingots were about 25-40 mm in diameter and 10-15 mm in height, and their structure was studied by x-ray diffractometry and scanning electron microscopy. The rectangular parallelepiped-shaped samples 2.5 × 2.5 × 5 mm in size cut from the central part of the ingots exhibit a high strength of about 2000 MPa, except for Ti60Fe40, and a certain ductility. The relatively low density of Ti (4.5 Mg/m3) implies high strength/density ratio for the studied alloys. These alloys are characterized by the low cost of the alloying element Fe and, compared to most of the high-strength non-equilibrium materials, do not require additional injection mold casting or rapid solidification procedures.
