| Popis: | Microstructure evolution and mechanical behavior of alpha/beta Ti-6Al-4V and Ti-6Al-4V-0.75Mo-0.5Fe titanium alloys during uniaxial compression to a height strain of 70% was studied. The plastic-flow response for both alloys is characterized by successive stages of strain hardening, flow softening, and steady-state flow. During compression the lamellae spheroidized to produce a globular microstructure with higher rate of globularization in Ti-6Al-4V-0.75Mo-0.5Fe. The globularization kinetics in Ti-6Al-4V-0.75Mo-0.5Fe was also found to be much faster than that in Ti-6Al-4V. This difference can be partially associated with different interphase energy due to doping of β-stabilizing elements. |
