摘　　要：结合撞击实验所获得的实验数据,从宏观和微观角度分别进行了战斗部用钛合金材料动态屈服压力和金相组织的分析,得到如下结论:随应变率的增加,动屈服应力、侧向膨胀等也增加;断裂表面变得更加不均匀,剪切边缘更加表面化,倾斜度更大,基体凹陷更深,更普遍;高速率加载试样的破坏区在更长的距离上扩展。Referring to the bumping experiment data,the dynamic yield pressure and phase structure of the titanium alloy material used in warhead is analyzed from macroscopical side and microcosmic side.Some conclusions are gained that the dynamic peak yield stress and side direction expansion is bigger with the strain rate increasing,the section becomes more nonuniform,the cut brim becomes apparent,the gradient is bigger and the damaged area enlarges within longer distance.
