    摘要: A method for consolidating a pre-form made of powder, comprising: (a) placing the pre-form between smart susceptors; (b) heating the smart susceptors to a leveling temperature by applying a varying low-strength magnetic field having a magnetic flux that passes through surfaces of the smart susceptors; (c) applying consolidation pressure to the pre-form at least during a time period subsequent to the temperature of the smart susceptors reaching the leveling temperature; and (d) while consolidation pressure is being applied, applying a pulsed high-strength magnetic field having a magnetic flux that passes through a surface of the pre-form. The strength and pulse rate of the high-strength magnetic field are selected so that the crystallographic phase of the pre-form will rapidly oscillate at a substantially constant temperature. The pulsed high-strength magnetic field is applied sufficiently long that superplasticity of the pre-form is attained during phase oscillation.

    摘要: A composite material with a ballistic protective effect having a first, outer layer made of a first steel alloy and at least one second layer which is arranged under the first layer and is made of a second steel alloy. The composite material with a ballistic protective effect allows for a reduction in the weight or the wall thicknesses of the composite material in comparison to conventional composite ballistic materials, by utilizing a first steel alloy of the first layer that has the following alloy constituents in percent by weight (% by weight): 0.06%≦C ≦1.05%, 0.05%≦Si≦1.65%, 0.3%≦Mn≦2.65%, 0.015%≦Al≦1.55%; Cr≦1.2%, Ti≦0.13%, Mo≦0.7%, Nb≦0.1%, B≦0.005%, P≦0.08%, S≦0.01%, Ni≦4.0%, and V≦0.05%, the remainder being Fe and inevitable impurities. The second layer of the composite material having a higher elongation than the first layer.

    摘要: It has been commonly believed that very thick gauge high strength aluminum alloy product such as AA2139 plate cannot be formed to the required sharp angles to form the highly protective underbody armor for the MRAP vehicles. The present process and method of manufacture provides a means for strategically combining the metallurgical process of manufacturing high strength aluminum alloys and the forming process of V shaped hull to improve the formability of the very thick gauge high strength alloy product so much that even the very thick gauge (thicker than 1 inch) plate can be formed to severe forming angles. This combined process allowed successful manufacturing of high performance V shaped hulls for the Mine Resistant Ambush Protected (MRAP) vehicles.
