摘要：
Microstructure evolution and its influence on the mechanical properties of (Ti65.5Fe34.5)(100-x)Nb-x (x=0, 3, 5 and 7) ultrafine composites has been investigated. The Nb-containing alloys exhibit simultaneously improved compressive mechanical properties, i.e. high yield (1.9-2.2 GPa) and fracture (2.2-2.6 GPa) strength together with large plasticity (6-13%), due to a favorable modulation of their ultrafine eutectic microstructure. The enhanced mechanical properties are strongly related to the length-scale, volume fraction and distribution of proeutectic phase as well as to the refinement and interphase coherency of the alternating ultrafine eutectic layers.
