摘要
通过对冲击破坏装甲钢组织分析,发现纯净装甲钢在冲击载荷下破坏过程中是在晶界交汇处(三叉点)产生裂纹源,然后相互连接的结果。同时根据材料强度理论和动态强化规律推导出材料微观结构参数与冲击速度之间的关系。
The microstructure has been analyzed to the armor steel with attacks, it was discovered that the destruction of armored steel under the impact load is first produces the crack source in the crystal boundary intersection point, then connects mutually. Meanwhile. the relationship between the material microscopic structure parameter and the impact speed has been concluded according to the material strength theory and the dynamic strengthened rule.
