Sn and Nb modified ultrafine eutectic Ti-Fe alloys with high strength and plasticity prepared by cold crucible levitation melting were tested in compression at room temperature. (Ti{sub 70.5}Fe{sub 29.5}){sub 93.15}Sn{sub 3.85}Nb{sub 3} alloy exhibited an ultimate compressive strength of 2.36 GPa at 15% plastic strain. Electron microscopy revealed that lamellar structures in Ti{sub 70.5}Fe{sub 29.5} alloy could be tailored by the addition of Sn and Nb to obtain a globular structure. The microstructural refinement, morphology of phase constituents, and their relationships to the mechanical properties are discussed.
