Powder injection molding (PIM), a relatively new material shaping process, uses the shaping advantages of plastic injection molding but expands the applications to numerous advanced engineering materials such as metals and alloys, ceramics, intermetalliccompounds, and composites. A number of these… More

"Current state-of-the-art ferrous products do not provide the desirable combination of ultra-high strength, high toughness as well as good corrosion resistance. For the carrier-based aircraft components, there is the urgent need for such an alloy.Currently that need is met by very-high strength… More

There is an urgent need for the development of innovative concepts of advanced warheads for air-delivered conventional munitions to defeat host of targets, both above and buried under the ground. The diverse need for the modern penetrator provides atremendous challenge for the material science and… More

There is currently an urgent need for the development of novel penetrator concepts capable of defeating hardened concrete reinforced targets. The use of a hard nose and high strength and high toughness steel can result in significant improvement in the penetrator performance. It follows, that the… More

Lead is a soft, low melting point, high density, and inexpensivve material that can be easily shaped. All these attributes have made lead useful in appplications such as bullets, fishing rod sinkers, weights for balancing tires, hunting shots, etc. In spite of all these attractive properties, lead… More

To produce a hypersonic flight vehicle, it is necessary to utilize an airbreating propulsion cycle. Most US aeropropulsion programs focus on the operation of a multi-mode engine with a ramjet and scramjet cycle that allows speeds from Mach 2 to over Mach 8. The testing of these engines is possible… More

Silicon nitride based materials have extremely attractive property combination and is ideally suited for gun barrel applications (increased life and reduced weight). In spite of the attractive properties, its use in gun barrels have been limited due to the inability of current processing techniques… More

Silicon nitride (Si3N4) based materials have the potential for use as rifled gun barrels that can provide a significant increase in barrel life, offer weight reduction, and enable the use of higher energetic propellants. Despite the potential, Si3N4 gun barrels have not been used due to the… More
