Embodiment

[0018] A novel Ni-Al-based all-metal energetic material, comprising the following steps: selecting Al 12 Mg 17 The powder is used as an added component, mixed evenly with Ni and Al powder, and the Al-Ni-based energetic material shell is prepared by cold spraying method; the Al and Ni powders are spherical, the molar ratio of the components is 1:1, and the Al 12 Mg 17 Irregular powder prepared by mechanical disintegration, Al 12 Mg 17 The powder content is 5% (mass fraction); the particle size is 10-30 μm.

[0019] The microstructure analysis, mechanical performance test and combustion performance analysis of the obtained energetic material shell were carried out; the results are:

[0020] The results of microstructure analysis showed that Al 12 Mg 17 The particles are evenly distributed, the density of the material is about 95%, and the density is about 4.5g / cm 3 . In terms of mechanics, adding Al 12 Mg 17 The dynamic compressive strength of the latter material is ab...

Abstract

The invention discloses a novel Ni-Al base all-metal energetic material and a preparation method thereof. When Ni-Al energetic metal composite material is prepared, proper amount of Al-Mg series intermetallic compound components including Al12Mg17 are added to improve the mechanical and chemical energy-releasing characteristic of the Ni-Al base all-metal energetic material. The formula can remarkably reduce the ignition temperature threshold of the all-metal energetic material and increases the combustion reaction speed and improves the reaction efficiency of active material while ensuring thematerial preparation efficiency.

Description

technical field [0001] The invention relates to a novel Ni-Al-based all-metal energetic material and a preparation method thereof, belonging to the technical field of preparation of all-metal active materials. Background technique [0002] Active materials (Reactive Materials) usually refer to energetic materials composed of two or more non-explosive solid substances that can react with themselves or air and release a large amount of chemical energy after ignition, usually with a high energy density And reaction temperature, it has a wide range of applications in the field of air defense, anti-missile, anti-radiation fragmentation warheads. When the active fragments penetrate the target, they can release a large amount of energy and produce a strong explosion or burning effect, which greatly improves the ability of the warhead to damage the target. Among them, in addition to better energy release characteristics, all-metal active materials also have certain mechanical prope...
