N2 - A high-density tungsten-zirconium-titanium (W-Zr-Ti) reactive alloy was prepared by powder metallurgy. This alloy exhibits high density, high strength, and violent energy release characteristics, resulting in outstanding penetration and ignition abilities. Dynamic impact experiment demonstrated its strain rate hardening effect, and the energetic characteristics were investigated by digital image processing technique and thermal analysis experiment. The results show that W-Zr-Ti reactive alloy performs compressive strength of 2.25 GPa at 5784 s−1 strain rate, and its exothermic reaction occurs at about 961 K. Based on the explosion test and shock wave theory, thresholds of enhanced damage effect are less than 35.77 GPa and 5.18×104 kJ/m2 for shock pressure and energy, respectively. Furthermore, the transformation of fracture behavior and failure mechanism is revealed, which causes the increase in compressive strength and reaction intensity under dynamic loading.
