Abstract

Abstract:

To reveal the synergistic enhancement mechanism of strength and plasticity of Zr-based BMG-W energetic fragments and elucidate their impact damage process, a series of Zr-based BMG-W energetic fragments with different spherical W particle contents are prepared by the spark plasma sintering method. The mechanical properties and damage performance of Zr-based BMG-W energetic fragments are thoroughly studied through quasi-static compression experiments and ballistic gun loading penetration experiments on double-layer targets. The research results show that the addition of W particles significantly improves the mechanical properties of Zr-based BMG-W energetic fragments. The Zr-based BMG-W energetic fragments with sintering temperature ranging from 370℃ to 385℃ and W particle content ranging from 20 vol.% to 40 vol.% have better strength and plasticity than pure BMG energetic fragments. Among them, the Zr-based BMG-40W energetic fragment prepared at 380℃ has the highest fracture strength and plastic strain, which are 2047.0MPa and 16.6%, respectively. The synergistic enhancement mechanism of strength and plasticity of Zr-based BMG-W energetic fragments includes two aspects: W particles hinder the rapid expansion of shear bands, promote their turning and proliferation, and delay the fracture failure of energetic fragment; the initiation and propagation of shear bands caused by modulus mismatch result in the formation of local plastic deformation zones in the BMG matrix near the W particles, reducing the spatial constraint of BMG matrix on the W particles. The W particles themselves undergo plastic deformation, delaying the fracture failure of energetic fragments. With the increase in W particle content, the damage performance of the Zr-based BMG-W energetic fragments increases first and then decreases, but all are better than pure BMG energetic fragments. Among them, the Zr-based BMG-40W energetic fragment has the strongest damage performance with an expansion ratio of 27.9. The impact damage process of Zr-based BMG-W energetic fragments mainly includes primary detonation, kinetic energy perforation, secondary detonation, and aftereffect damage.
