Shear Form Fabrication of Liners for Heat Projectiles
Abstract
In an effort to optimize the shear form fabrication process, six groups of shaped charge liners were manufactured, Each group contained a single change in the shear form process. The changes included different starting material, apex shape, and anneal cycle. The penetration performance of the six groups of liners were evaluated by static tests, triple flash radiograph tests, and metallurgical analysis. The evaluation was then used as the basis for the establishment of a process which optimized costs and performance. A quantity of these optimized liners were fabricated and tested as before to characterize penetration performance and metallurgical characteristics. This report and the contractor's Description of Manufacture (DOM) report have been prepared to outline this optimum process which was developed to economically produce a complex shaped charge copper liner for use in HEAT projectiles fired from tank cannons. Note to page 10: Test results are presented as + or - with respect to 17 inch minimum required penetration of the M456A2. Penetration results were declassified in accordance with Memorandum for AMSTA-AR-PSI signed by Colonel Gary Payne, dated 30 April 1999.
