摘要
为了探讨A-Ⅸ-Ⅱ压装炸药的失效模式,通过扫描电镜、工业CT分别对低装药密度、中装药密度和高装药密度A-Ⅸ-Ⅱ炸药装药在高低温循环温度应力施加下的结构稳定性进行分析研究,并讨论了裂纹和"渗油"两种结构失稳模式。研究表明A-Ⅸ-Ⅱ压装炸药的主要失效模式是药柱产生裂纹,"渗油"引起的结构失稳是否会导致装药失效还有待进一步研究。
Aimed at the failure modes analysis of pressed charge A-Ⅸ-Ⅱ, the structure stability of A-Ⅸ-Ⅱ with low, middle and high charge density, which experienced high-low temperature cyclic test, was studied through SEM and industrial CT. And two failure modes of crack and exudation were analyzed. The study results indicated that crack is the main failure mode of pressed charge A-Ⅸ-Ⅱ, whether exudation would lead to failure should be studied furthermore.
