摘　　要：为了提高锆基非晶合金反应材料冲击反应产生的烧蚀毁伤效能,用热电偶测量非晶破片撞击准静态腔室后容器内温度场的变化,研究元素组分对破片冲击反应烧蚀特性的影响。而且力学性能对于其侵彻能力和释能能力起重要作用,为分析钛和铌对反应材料力学性能的影响,开展了锆基非晶合金的准静态压缩试验和SHPB杆动态压缩测试。试验结果表明:钛能为非晶破片提供较大的塑性变形能力,铌能提升非晶破片的弹性模量,随着加载应变率增加,两种材料的脆性增加而塑性降低;温差峰值可以相对表征非晶破片的烧蚀效能;在相同条件下,锆钛基破片对目标的烧蚀作用优于锆铌基破片。In order to improve the ablation efficiency caused by the impact reaction of zirconium-based amorphous al-loy reactive materials,the temperature field in the container was measured by thermocouple after the amorphous fragments impacted on the quasi-static chamber.Effect of element composition on the impact reaction ablation char-acteristics of fragments was studied.In order to analyze the effect of titanium and niobium on the mechanical proper-ties of reactive materials,quasi-static compression test and SHPB bar dynamic compression test of zirconium-based amorphous alloy were carried out.The experimental results show that titanium can provide greater plastic deforma-tion ability for amorphous fragments,niobium can increase the elastic modulus of amorphous fragments,and the brittleness of the two materials increases and the plasticity decreases with the increase of loading strain rate.the peak temperature difference can relatively characterize the ablation efficiency of amorphous fragments;under the same conditions,the ablation effect of zirconium-based fragments is better than that of zirconium-niobium-based fragments.
