摘要: 建立了用于轻气炮上冲击压缩实验的材料预加热系统及相关实验技术。介绍这一系统的原理、构造及操作。利用这一系统，在加载幅度8 GPa的恒定载荷下，得到了初始温度300～980 K范围内HR-2抗氢不锈钢的动态响应特性，包括层裂强度、Hugoniot弹性极限、卸载声速及它们随温度的变化规律。Abstract: A set of material preheating system used in the light gas gun shock compressed experiment has been built up. The principle of structure and operation of the system are introduced. Using this system, the shock response, including spall strength, Hugoniot elastic limit and unloading sound velocity, of HR-2 stainless steel with initial temperature range 300~980 K under fixed shock amplitude of 8 GPa is obtained, and their variations with temperature are deduced in this paper.
