AB The extensive industrial employment of titanium is hindered by its high production costs wherereduction of these costs can be achieved using cheap alloying elements and appropriatealternative processing techniques. In this work the feasibility of the production of low-costtitanium alloys is addressed by adding steel to pure titanium and processing the alloys by powdermetallurgy. In particular, a spherical 4140 LCH steel powder commonly used in metal injectionmoulding is blended with irregular hydride-dehydride Ti. The new low-cost alloys are colduniaxially pressed and sintered under high vacuum and show comparable properties to otherwrought-equivalent and powder metallurgy titanium alloys. Differential thermal analysis and Xray diffraction analyses confirm that Ti can tolerate the employment of iron as primary alloyingelement without forming detrimental TiFe-based intermetallic phases. Thus, the newly designedα+β alloys could be used for cheaper non-critical components.
