| Abstract Scope |
Titanium alloys are crucial lightweight materials widely used in structural applications. Powder metallurgy (PM) enables efficient and economical manufacturing, making Ti-Fe alloys particularly attractive for cost-effective civilian applications. This study focuses on designing new titanium PM alloys by incorporating 3-5 wt% iron, an abundant and economical alloying element, to enhance sinterability and densification during PM processing. Experimental results show that the addition of iron significantly improves sintered density and results in favorable mechanical properties in the as-sintered condition, including high strength coupled with good ductility. Detailed microstructural analysis reveals that iron contributes to the formation of a lamellar microstructure. By optimizing alloy composition and PM processing parameters, including sintering temperature and atmosphere, these alloys achieve high densities and exhibit mechanical properties comparable to PM Ti64. These results demonstrate the feasibility of using Fe-alloyed PM titanium alloys in civilian sectors, offering substantial cost advantages over traditional wrought methods. |
