摘要

摘要: 利用二级轻气炮技术并结合对称碰撞方法对铁样品进行了冲击加载，通过测量铁/蓝宝石的界面光谱辐射亮度获得该界面的冲击温度。实验中，采用了新的样品/窗口界面制备途径和更加可靠的高温计标定方法，有效地消除了直接接触界面的尖峰辐射现象，观测到了Fe/Al2O3接触界面的稳定辐射。实验结果表明，在164 GPa冲击压力下Fe/Al2O3的界面温度为（3 950180） K。

Abstract: The iron sample is symmetrically impacted by a high speed flyer of the same material, which is launched by use of two-stage light-gas gun. The temperature of the interface between iron and sapphire is determined by measuring the spectra illuminaton. In experiment, a new technique is applied to prepare the bulk iron/sapphire interface, and an improved in-situ method is used to calibrate the pyrometer. As a result, the peak radiation from the directly contacted interface is effectively diminished, and the stable emission from the ideally intacted interface of Fe/Al2O3 is observed. The result shows that the Fe/Al2O3 interface temperature corresponding to the shock pressure of 164 GPa is (3 950180) K.
