Fiscal Year: 2011
Title: Net Shape Fabrication of Novel Projectile Materials Using Rapid Combustion Driven Ultra-High Pressure Powder Compaction (CDC) Manufacturing
Agency: DOD
Contract: N00167-11-P-0015
Award Amount: $79,980.00
 

Abstract:

The major objectives of the Phase I effort will be focused on CDC high pressure compaction/fabrication, post-processing, testing and materials performance/baseline preliminary material modeling of the kinetic behavior of the projectile material compositions based on select geometry and CDC materials properties. CDC projectile/warhead fragment materials include tungsten alloys, Hf/Al, W/Al, Al/Boron, Hf/Zn, Zr/Zn, Zr/Al, or Ta/Al, Mo/Al, and select materials with boron, molybdenum oxide and/or sulfur including some polymer matrix composites indicating the potential for process flexibility. Select geometrical shapes such as 1 inch diameter cylinders/disks with 1 inch thickness will be fabricated using the available 300 ton CDC press and existing die/punch assemblies for initial exploration. Compositions will be optimized in consultation with OSD sponsors to obtain varying densities closer (e.g., 7 g/cc or higher). Appropriate experimental process optimization at much higher compaction pressures (e.g., 50 to 150 tsi) will be developed to obtain projectiles of controlled porosities as an integral part of Phase I, Phase I option and Phase II. Key CDC process optimization, suitable as-pressed higher density parts and /or any other less thermal processing sintering/heat treatment responses, net shaped part quality, microstructural/microchemistry properties, and mechanical properties such as hardness and other strength durability properties at room temperature will be evaluated in Phase I. In Phase II, scaling up, materials/manufacturing of advanced projectiles of desirable geometries for reactive fragment warhead components such as multiple-pressing of several pellets, projectile assemblies, spheroidal shaped warheads etc will be planned and the developed CDC parts after optimum processing conditions. One of the potential collaborators in the proposed SBIR is ATK.
