Research of the Anti-penetration Mechanism for Titanium Alloys Armor Based on 3D Optical Scanning Technology
To reveal the anti-penetration mechanism of titanium alloys armor quantitively, the volumes of the front crater region, the ductile hole-enlargement region, as well as the back caving region of Ti-6A1-4V alloy and β20C alloy are measured via 3D Optical scanning technology.The experimental results show that β20C alloy, of which the volume fraction of ductile hole-enlargement region is 51%, 10% larger than that of Ti-6A1-4V alloy, presents a better ballistic performance.It is found that the ballistic performance is closely related to the volume of ductile hole-enlargement region and a relatively larger ductile hole is beneficial to improve the ballistic performance.However, the ballistic performance shows no improvement with increasing the volume of front crater region.
