Dual-hardness titanium alloy composite armor
Description
The ballistic characteristics of a dual-hardness titanium alloy composite armor consisting of a hard Ti--3 Si--3 Fe--0.5N or Ti--3 Si--2 Fe--3 Mo--0.75N front-face alloy diffusion/roll bonded to a tough Ti--7 Al--2.5 Mo back-face alloy were evaluated using 30-cal AP projectiles. Performance, which was interpreted in terms of ballistic limit and spall resistance, was correlated with front- and rear-face hardness levels, alloy composition and structure, thickness ratios, and areal density. When compared with homogeneous titanium alloy armor, composites whose front face constitutes 30 percent of the total thickness and whose hardness is greater than or equal to R/sub c/ 58 were found to provide superior ballistic protection against small-caliber projectiles
