THE PRODUCTION OF THIN-WALLED SHAPED CHARGE LINERS BY THE DIE CASTING PROCESS

摘要

Procedures were developed for the die casting of shaped charge liners for Rocket, HE, AT, 3.5 inch, U28A2. Cones were die cast in one zinc and two aluminum die casting alloys. In the aluminum al- Ioys, cones were produced with wall thicknesses of 0.100, 0.130, and 0.160 inch so that an evaluation of the effect of mass on the ballistic performance could be made. Mechanical property data appear in- conclusive because of the geometry of the test specimens. Radio-graphic and metallographic examinations showed that the casting were sound. The dimensional tolerances set forth in the applicable drawings were met.
