摘　　要：研究了钨合金破片对低碳钢板高速侵彻过程中的失效行为及诱发机制。通过弹道枪实验获得93W、95W 2种球形钨合金破片以大于1500 m/s的速度对Q235A钢板侵彻后的物理形态,对侵彻后受损破片进行了扫描电镜(SEM)观察与分析。结果表明:对于Q235A钢板,钨合金破片以大于1500 m/s的速度侵彻后,93W钨颗粒是韧窝型穿晶断裂,而95W钨颗粒是准解理型穿晶断裂;93W、95W合金破片局部均会发生熔化,50μm钨颗粒熔化冷凝后生成10μm以下的微米、亚微米尺度球形颗粒紧密排列,宏观上表现为破裂碎块的整体侵彻。The failure behavior and inducement mechanism of tungsten alloy fragments penetrating low carbon steel plate at high velocities were investigated. The physical forms of 93 W and 95 W fragments after penetrating the low-carbon steel target at the velocities higher than 1500 m/s were obtained by ballistic gun experiments. Scanning electron microscope（SEM） was used to analyze damaged tungsten alloy fragments after the penetration. The result shows that for low-carbon steel plate, when the penetration velocity of the tungsten alloy fragment is higher than 1500 m/s, 93 W tungsten particle is dimple-type transgranular fracture, while 95 W tungsten particle is quasi-cleavage transgranular fracture. Both 93 W and 95 W fragments melt partially, and the 50 μm tungsten particles melt and condense as less than 10 μm spherical particles and arrange tightly. The macro phenomenon is the penetration of the whole damaged particles.
