Abstract
The invention provides a high-energy-content amorphous alloy material, which contains one or more of the following elements: mg, Al, La, Ce, Zr; and the heat value of the high-energy-content amorphous alloy material is 0.7-30 kJ/g, preferably 10-25 kJ/g. The amorphous alloy high-energy-content material provided by the invention has a lower ignition point, retains a higher combustion heat value, and is safer, lower in cost and higher in yield compared with crystalline alloy nano powder. The amorphous alloy high-energy-content material can be applied to the fields of explosives, leads, fireworks, solid propellants and the like.
Description
Technical Field
The invention belongs to the field of material preparation, and particularly relates to a high-energy-content amorphous alloy material, and a preparation method and application thereof.
Background
An energetic material is a metastable material with high energy, which releases a large amount of heat when subjected to a certain external stimulus. Specifically, energetic materials are compounds or mixtures having explosive groups or containing oxidants and combustibles, capable of independently carrying out chemical reactions and outputting energy, and are important components of military explosives, propellants and rocket propellant formulations. At present, the non-metal energetic material is widely used for explosives or fuels due to low burning point, but the combustion heat value is only within 3000-6000J/g. The crystalline metal energetic material can have a high combustion heat value of 7000-30000J/g, and is developed or applied to rocket solid propellants, submarine underwater propellants and firework display in a small amount. However, the high ignition temperature of crystalline metals prevents subsequent applications of such energetic materials. Taking aluminum as an example, although the calorific value of aluminum can reach 30000J/g, the actual ignition temperature thereof is higher than 2000 ℃, thus making the crystalline pure aluminum energetic material difficult to ignite and apply.
In order to maintain a high combustion heat value of the metal and significantly reduce the ignition temperature, the existing strategy is to pulverize and sufficiently reduce the size of the powder, and specific approaches are chemical synthesis, mechanical alloying, thermal hydrogen treatment, catalysts and the like. The research shows that after the metal aluminum and the metal magnesium are processed into nano particles through powdering, the ignition temperature of the metal aluminum and the metal magnesium can be obviously reduced, and the combustion efficiency can be improved. Many metal powders exhibit liquid-like characteristics when the diameter of the nanoparticles is below ten nanometers. However, the powdering method has high cost, low yield, poor stability, low safety, high risk in the production, storage and transportation of metal powder, and is not suitable for practical use, and therefore, it is necessary to develop other means for utilizing metal as energetic material.
Amorphization of the alloy may provide another route to the preparation of metallic high energy materials. The amorphous alloy material can freeze the liquid structure of the alloy in the solid, store a large amount of liquid energy in the solid, and store gas with small molecular size such as hydrogen or oxygen in the solid, thereby improving energy, increasing chemical activity, reducing the ignition point of the material, ensuring more sufficient combustion reaction and improving the combustion heat value of the material. Meanwhile, as a typical metastable material, the amorphous alloy can stably maintain high energy for hundreds of years at room temperature, and the explosion danger of alloy particles caused by instability is avoided. The existing research shows that the amorphous alloy strip prepared by a quenching and strip-casting method is easier to be oxidized. By testing the oxidizability of a series of alloy samples, amorphous alloys > quasicrystalline alloys > crystalline alloys. This indicates that the amorphous state is the most suitable material for combustion in the alloy. In addition, the amorphous alloy strip, the filament and the powder have mature preparation process, low cost, large yield and good mechanical property, so the amorphous alloy strip, the filament and the powder are suitable for being used as novel high-energy materials.

Test example 1
This example is used to illustrate the use of the product of the present invention as an electric primer for an electronic detonator.
Amorphous powder is added into a basic formula (potassium chlorate/charcoal powder/polyvinyl alcohol: 80/20/proper amount) of a common electric ignition powder head, and the influence of the content and proportion of the amorphous powder on the ignition time of the electric ignition powder head is researched.
