Outline
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 (3 950±180) K.
