Abstract

The relatively low density of Ti (4.5 Mg/m3) implies high strength/density ratio for Ti-based alloys. A composite Ti65Fe 35 alloy produced in the shape of arc-melted ingot of about 20mm in diameter and 10mm in height exhibits a high mechanical strength of 2.2 GPa at 6.7% ductility and a Young's modulus of 149 GPa. Its microstructure consists of the cubic TiFe phase and a supersaturated BCC β-Ti solid solution. The formation of a supersaturated β-Ti solid solution and the disperse eutectic structure obtained result in a high strength of the Ti-Fe alloy which in addition to that has much higher ductility compared to that of nanostructured and glassy alloys. The Ti-Fe alloy is characterized by low cost of the alloying elements and does not require an additional injection mould casting procedure.
