9360488古德曼使用高能(1-5 MeV)、高功率(250kW-1 mW)电子束，可以低成本制造独特的高温材料，而这些材料不是用传统制造方法经济地制造出来的。采用该工艺可制备的材料包括具有梯度热性能和力学性能的镍基高温合金以及陶瓷增强的TixAl和NixAl金属基复合材料。电子束制造过程熔化和固结纯或合金粉末、编织或颗粒增强材料和金属箔，以产生净形状的结构。科学研究实验室开发了新一代脉冲直线感应加速器(LIA)，这种加速器可以可靠、经济高效地生产具有高能电子束(Heeb)材料制造所需参数的高平均功率电子束。这些加速器的独特功能包括高重复频率(5000pps)全固态脉冲功率驱动器，这使得这些加速器可以扩展到兆瓦功率级别，加速器的资本成本约为2美元/瓦。***！！！F(Times New Roman符号&amp；Arial```“h：：/抽象Maceo Hart Maceo Hart

9360488 Goodman The use of high energy (1-5 MeV), high power (250 kW-1 MW) electron beams allows the low cost fabrication of unique high temperature materials which are not economically manufactured using conventional fabrication methods. Materials which can fabricated using this process include nickel-based super alloys with graded thermal and mechanical properties and ceramic-reinforced TixAl and NixAl metal-matrix composited. The electron beam fabrication process melts and consolidates pure or alloy powders, woven or particulate reinforcement material and metal foils to produce net shape structures. Science Research Laboratory has developed a new generation of pulsed linear induction accelerators (LIA) which allow reliable, cost efficient production of high average power electron beams with the necessary parameters for high energy electron beam (HEEB) material fabrication. Unique features of these accelerators include high repetition rate (5000pps) all-solid-state pulsed power drivers which make these accelerators scalable to megawatt power levels at a capital cost of the accelerator is approximately $2/Watt. *** ! ! !
