摘要

A 70 volume percent tungsten/30 volume percent uranium penetrator material was fabricated by infiltrating uranium into a porous tungsten preform. This material is equivalent to a matrix substitution of uranium for nickel and iron in a conventional tu1gsten heavy alloy. The ballistic performance of the as-cast materials were compared with conventional U-3/4 Ti material at Los Alamos and the U.S. Army Ballistics Research Laboratory (BRL) Ballistic testing of the two materials showed them to be equivalent It is believed that the ballistic performance of U-3/4 Ti as related to early localized failure caused by adiabatic shear(1) Target postmortem evaluation was undertaken to determine if the same mechanism applies to the uranium-tungsten penetrator material. Areas of analysis included the penetration channels in semi-infinite rolled-homogeneous armor(RHA), and residual penetrator tubes and penetrator stubs from the BRL target. Results from the uranium-tungsten material were then compared to similar ballistic tests using U-3/4 Ti Observations in the uranium-tungsten material indicate that localized failure in the uranium matrix, similar to U-3/4 Ti, was the dominant mechanism for penetrator performance.
