高能快速成型的空心装药药形罩可以产生高延展性射流。为了进行研究，我们用数值最优化设计法设计出了一种加工条件相对简单的空心装药结构。高能快速成型的药形罩锻件是用电弧熔铸的钼棒料加工而成的。这种锻件经热处理和机加工，生产出的药形罩消除了各种应力并进行了重结晶．用三倍远距离闪光射线照相对所加工的空心装药射流的延展性进行了全面测定，通过对经机加工并重结晶、能产生极佳射流延展性的药形罩的研究。观察到了射流延展性的主要趋势．到目前为止，我们观察到的钼射流中最高的延展性与典型的铜聚能装药的延展性相当。
High-energy, rapid prototyping hollow charge chests create high-ductile jets. In order to carry out the research, we designed a hollow charge structure with relatively simple processing conditions by numerical optimization design. High-energy, rapid prototyping forgings are machined from arc-cast molybdenum bars. The forgings are heat-treated and machined to produce a mask that eliminates all stresses and recrystallizes. The ductility of the processed hollow charge jets was fully determined by tripled, long-range flash radiography and the study of a drug-shaped mask with excellent jet-ductility was produced by machining and recrystallization. The main trend of jet ductility was observed. So far, the highest ductility we observe for molybdenum jets is comparable to the ductility of a typical copper charged charge.
