爆轰加载下金属样品的熔化破碎现象诊断*OA北大核心CSCDCSTPCD
Experimental diagnostic of melting fragments under explosive loading*
本文在传统Asay窗技术基础上设计发展了一种用于诊断熔化状态下金属样品表面附近一定厚度区域内熔化破碎现象的Asay-F窗技术，较准确给出了该区域熔化破碎物质的质量和密度分布信息，并与表面微喷和固体层裂片的特征进行了比对分析，为熔化破碎现象的形成机理认识和物理建模提供了重要实验数据。而且研究表明Asay-F窗技术可在一定程度上弥补目前熔化破碎现象主要依靠高成本质子照相技术诊断的不足。
We have conducted experiments to study the melting fragments from explosively shocked melting Pb targets. Based on the traditional Asay-Window technique, Asay-F-window was designed, which is suitable to investigate high-density melting fragments of metal sample. The areal mass and volume density of melting fragments from the Pb target were presented, which is also compared with that of micro-jetting and solid spallation. The results may contribute to the und…查看全部>>
