DRX-Induced Solid-State Flow and Projectile-Target Mixing During 001 Single-Crystal Tungsten Rod Penetration into Steel Targets

摘要

Residual [001] single-crystal W rods penetrated into steel targets have been examined by light and electron microscopy. The post-impact residual penetrators examined using energy-dispersive x-ray mapping, revealed target and penetrator mechanical mixing. Considerable intercalation activity was found to concentrate specifically within the material being eroded by DRX-assisted flow. The solid-state flow features (including shear bands) facilitate the mixing of the two. Residual microstructures obtained within the penetrator suggest localized melt zones due to thermal instabilities caused by the turbulent behavior in the high-pressure regime.
