冲击加载下石英玻璃对苯的冲击相变诱导

Phase Transformation Induction of Benzene by Quartz Glass Under Shock Compression

在一级轻气炮上利用弹载光源技术,对苯在多次冲击加载下进行在线测量,通过观察光的透射率变化来研究苯的冲击相变。实验表明冲击加载下石英玻璃对苯的冲击相变起到了诱导作用,分析认为是石英玻璃界面与苯的相互作用,为苯的相变提供了成核条件。

In this paper,a missile borne light source in-situ test technique was used in gas gun.The shock phase transition of ben⁃zene was studied by observing the change of light transmittance on-line measurement under multiple shock compression.The results show that the shock phase transformation of benzene is induced by quartz glass under shock compression.It is considered that the inter⁃action between quartz glass and benzene provides the nucleation condition for the phase transformation of benzene.
