摘要

A phenomenon of shock wave reacceleration was studied when Ti+Si reactive powder is loaded by a high-speed flyer. The self-propagating reaction in the Ti+Si reactive powder was triggered by the high speed impaction of the flyer launched by a two-stage gas gun. In the process of self-propagating reaction, a strand of optical fiber and the electric pins were used to measure the velocity of shock wave propagation. The experimental results showed that the initial velocity of shock wave in the reactive powder was a few hundred meters per second, and then it decreased obviously with the increase of propagation distance. This phenomenon was also verified in the process of a pure Si powder loaded by a shock, while the phenomenon of shock wave reacceleration was not observed in the Ti+Si reactive powder.
