摘要

Dynamic recrystallization (DRX) of tungsten was investigated through the microstructural examination of a recovered shaped charge slug, using both optical and transmission electron microscopy. The microstructure was refined, indicating the DRX process occurred during deformation. No twins or elongated subgrains were observed due to the extremely high strain rate deformation process. This proves that the DRX process was dominated by dislocation movements. Compared with previous reports of copper and tantalum shaped charges, the tungsten liner deforms more like copper than tantalum.
