摘要
对某反应式圆柱形破片在静态压缩时出现0°、45°和两角度混合的三种压缩断裂方式进行了研究;利用扫描电镜和电子衍射分别对0°、45°和两角度混合的断面与截面进行扫描分析及能谱分析。结果表明:在0°方向断口主要为解理断口和准解理断口,45°方向为韧窝断口。还利用"史密斯理论"揭示了破片断裂机理。
A type of reaction cylinder fragment appeared three fracture modes of 0°,45° and mixture of two angles when it was under the static compressive load. This study used SEM and XRD to analyze fracture and sections of 0°,45° and mixture of two angles. Furthermore, ＂Smith＇ s theory＂, was adopted to analyze fracture mechanism of fragment.
