Abstract

The compressive behavior of pressing sintering Zr-W multifunctional energetic structural material was tested at different strain rates by using material testing machine and split Hopkinson pressure bar (SHPB) system. A constant strain rate dynamic loading can be obtained by combination of attaching a strain gauge directly to the sample and employing the pulse shaping technique. Test results show that Zr-W material appears good linear elasticity both under quasi-static and dynamic loading, and its elastic modulus is about 186 GPa, not so sensitive to stain rate effect. The Zr-W material presents high-strength and brittle which is attributed to the W₂Zr sintering product phase, and it can fragment, react and rapidly release high amounts of energy under strong impacting load. The results show that the Zr-W material has high energy, and its dynamic failure strain and failure strength increase with the strain rate increasing.
