中文摘要:
      研究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。通过弹道枪试验获得93W、95W两种球形钨合金破片以大于1500m/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1500m/s的速度侵彻后,93W是钨颗粒韧窝型穿晶断裂,95W是钨颗粒准解理型穿晶断裂;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。

英文摘要:
      The failure behavior and inducement mechanism of tungsten alloy fragments penetrating low carbon steel at high projectile velocities are investigated. The physical forms of 93W and 95W fragments after penetrating the low-carbon steel target at the velocities that higher than 1500m/s were obtained by using ballistic gun experiments. Using Scanning Electron Microscope (SEM) 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 1500m/s, 93W tungsten particle is dimple-type transgranular fracture, 95W tungsten particle is quasi-cleavage transgranular fracture; Both 93W and 95W fragments were melted partially, the 50μm tungsten particles melted and condensed as less than 10μm spherical particles and arranged tightly. The macro phenomenon is the penetration of the whole damaged particles.
