The tensile properties, impact properties, dynamic mechanical property and ballistic performance were tested for four kinds of typical titanium alloys of TA15、Ti-6432、TC21 and Ti-15Mo. The microstructure of the different alloying sheets after penetration test of bullet were analyzed. The results show there is no direct relationship between impact properties and tensile properties for four alloys. For tensile properties and dynamic mechanical property, there is a law that high tensile strength is corresponding to high dynamic compression rheological stress and high elongation is corresponding to high homogeneous plastic strain. However, this law is only a reflection of the trend, and there is no corresponding proportional relationship between the specific values. For dynamic performance and ballistic performance, the order of dynamic properties of the four alloys is TC21＞ TA15＞Ti-15Mo＞Ti-6432, the ones of ballistic performance is TC21＞TA15＞Ti-6432＞Ti-15Mo. From the specific value, the difference of dynamic properties for four alloys is obvious but the ones of penetration depth is not obvious, which is at the same level. Besides, the penetration depth of Ti-15Mo is obviously larger than that of other alloys. Which shows that the dynamic performance can not fully reflect the ballistic performance. The above results are mainly related to different microstructure types and different deformation damage mechanisms in the damage process.
