N2 - Energetic structural materials (ESMs) have high energy density and the rapid energy release characteristics, which has been drawn much attention in the past decades. Under dynamic loading, the chemical reaction will be inspired. However, its initiation and reaction are still not known well. Our work focused on the performance of Ni-Al ESMs, which keep both good mechanical properties and high energy release. Ni-Al ESMs was successfully prepared by explosive consolidation technique, which was useful to improve the interface quality among the particles. The microstructure was designed for Ni continuous phase (Nicp) and Al continuous phase (Alcp). The feature was analyzed by scanning electron microscopy. Quasi-static and dynamic compression tests were done to understand the mechanical properties. By impact-induced initiation, the effect of the microstructure was analyzed. Also, the additive was used to optimize the performance of Ni-Al ESMs. The effect of the additive on the impact-induced initiation was analyzed.
