摘要

This paper aimed to study the quasi-static and dynamic properties of the titanium alloy with nominal composition Ti-4Al-3V-0.6Fe-0.2O. The ingots Ti-4Al-3V-0.6Fe-0.2O alloy were forged into slabs of 32 mm thickness by one heat above T_(β-transus) temperature and one heat below T_(β-transus) temperature, and then rolled into plates of 8 mm thickness by one heat below T_(β-transus) temperature. The quasi-static tensile properties were tested by MTS? testing system at strain rate of 10~(-1) s~(-1). The dynamic compression properties were tested by Split Hopkinson Pressure Bar system at strain rate of 3000±200 s~(-1). The results show that the quasi-static properties of the Ti-4Al-3V-0.6Fe-0.2O plate are comparable to ATI 425TM alloy plate and commercial Ti-6A1-4V plate. The average dynamic flow stress of Ti-4Al-3V-0.6Fe-0.2O plate is comparable to ATI 425~(TM) alloy plate, over lOOMPa higher than that of Ti-6A1-4V plate. The maximum strain during homogeneous dynamic plastic deformation of Ti-4Al-3V-0.6Fe-0.2O plate is approximately 15 ~ 20% higher than that of ATI 425? alloy plate, and is approximately 80% of that of Ti-6Al-4V plate.
