Description
Technical Field
The invention belongs to the technical field of preparation of energetic structural materials, and particularly relates to a Ti-based all-metal energetic structural material, a preparation method and application thereof.
Background
The energetic structural material is a structural function integrated material with mechanical property and energy release characteristic, can have enough kinetic energy and strength to break down a target in the process of damaging the target, simultaneously generates severe chemical reaction under the action of impact load, releases huge energy, further enhances the damage effect, and greatly improves the damage capability of the fighter part.
Energetic structural materials are typically required to be in service under high velocity impact conditions, first to be launched at high velocity under the action of a high explosive, then to break down the target by kinetic energy when flown to the target, after passing through the target, to initiate chemical reactions due to friction and plastic deformation, releasing energy. According to the service conditions, the energetic structural materials are required to meet three basic requirements: (1) the high-strength plastic is provided to ensure that the explosive has a complete structure when the explosive is detonated; (2) has high density to meet the requirement of kinetic energy breakdown; (3) has high reactivity, so as to realize rapid release of a large amount of energy after target penetration and damage of the target.
In the prior researches, the Al-based all-metal energetic structural materials are a type of energetic structural materials which are more researched, but the compressive strength of most of the Al-based energetic materials is generally not more than 500MPa, so that the detonation integrity of the Al-based energetic structural materials is difficult to maintain. According to the study by Wei et al (doi: 10.1016/j.actamat.2011.10.027), the mechanical properties of the base metal determine the upper limit of the overall material strength. Compared with Al and Al alloys, the Ti and Ti alloys have more excellent mechanical properties, the yield strength of pure Ti is about 284 MPa, the yield strength of TC4 is about 862MPa, and the yield strength of Al and Al alloys is about 70-400MPa, so that the Ti-based material has more advantages in the aspect of keeping detonation integrity. In addition, the thermal conductivity of Ti and Ti alloy is only about 6 percent of that of Al, and heat accumulation is easier in the impact process, thereby achievingConditions for initiation of metal combustion. Meanwhile, ti has higher combustion heat value (about 19.8 kJ/g) in oxygen, can release huge energy during reaction, and has the potential of being used as a matrix of a metal-based energetic structural material. However, the Ti density is only 4.5g/cm 3 Therefore, development of a novel Ti-based energetic structural material with high density and excellent mechanical properties is needed.
Disclosure of Invention
Aiming at the defects existing in the prior art, the invention provides a novel Ti-based all-metal energetic structural material, a preparation method and application thereof. Compared with the traditional Al-based material, the Ti-based all-metal energetic structural material has the advantages of high density and high plasticity, and meanwhile, has good ignition performance, good reaction initiation performance under impact conditions, and the preparation method is simple and efficient.
Specifically, the invention provides the following technical scheme:
a preparation method of a Ti-based all-metal energetic structural material comprises the following steps:
1) Preparing metal powder, wherein the metal powder comprises the following components in percentage by mass: ti 40-65% and density 11.5g/cm 3 35% -60% of the high-density metal, and 0-5% of other metal or metalloid selected from at least one of Al, mg, fe, si, B;
2) Filling the metal powder into a sheath, compacting, vacuumizing and sealing;
3) And (3) placing the sealed sheath into a hot isostatic pressing device, and preserving heat and pressure for 0.5-3.0. 3.0h at the temperature of 850-950 ℃ and the pressure of 100-150MPa to obtain the Ti-based all-metal energetic structural material.
The Ti-based material has obvious microscopic interfaces due to the addition of heterogeneous metals (high-density metals) and careful design of technological parameters, especially temperature and time, of hot isostatic pressing sintering, so that the obtained Ti-based all-metal energetic structural material has a pure Ti area and a pure high-density metal area, also has a Ti-high-density metal diffusion area with proper thickness and good interface combination, thereby having certain mechanical properties, being easier to break into small blocks under impact conditions, utilizing the reaction among components to initiate oxidation combustion, and being beneficial to full combustion to release energy. Taking the Ti-based all-metal energetic structural material shown in the embodiment 1 of the invention as an example, a composition gradient structure of a pure Ti region, a Ti-Ta diffusion region and a pure Ta region is formed in a microstructure (see (a) in fig. 3), so that the bonding strength of a micro interface between Ti and Ta is enhanced, the prepared material has excellent compression performance and tensile performance in a macroscopic sense, a pure Ti phase and a pure Ta phase are reserved, and the material is favorable for full crushing under the impact condition.
Furthermore, the density, the process performance or the reaction initiation condition of the Ti-based full-metal energetic structural materials can be further optimized by adding a proper amount of other metals or metalloids selected from Al, mg, fe, si and/or B into the metal powder.
Preferably, in step 1), the Ti is present in the form of Ti powder and/or Ti alloy powder.
Preferably, in step 1), the high-density metal is one or two or more of W, ta, re, hf.

According to the invention, a proper amount of MgAl intermetallic compound is further added on the basis of Ti+high-density metal, so that the reaction initiation performance can be obviously improved, and the Ti-based all-metal can be suitable for application scenes with the landing speed below 1100m/s (the smaller the landing speed is, the higher the requirement on the reaction initiation performance is); by further adding a proper amount of metal Mg on the basis of Ti+high-density metal, the Ti-based all-metal can give consideration to high reaction initiation performance and strength performance, and is simultaneously suitable for application scenes with the landing speed below 1100m/s and above 1800m/s (the higher the landing speed is, the higher the energy release efficiency is, the lower the requirement on the reaction initiation performance is, but the higher the requirement on the strength is).
Preferably, in the step 1), the particle size of the metal powder is 0.5-70 μm, the purity is more than or equal to 99%, and the shape is one or more than two of spherical, polygonal and dendritic; more preferably spherical.
Preferably, in the step 2), after the tapping treatment, the tap ratio (ratio of tap density to theoretical density) is 0.60 or more.
Preferably, in step 2), after the vacuuming treatment, the vacuum (absolute pressure) is 1×10 -2 Pa or below.
Preferably, in step 3), after the hot isostatic pressing process, the method further comprises a step of removing the sheath.
The invention also provides a Ti-based all-metal energetic structural material which is prepared according to the preparation method.
The invention also provides the application of the Ti-based all-metal energetic structural material or the Ti-based all-metal energetic structural material prepared by the preparation method in the killer cells with the targeting speed below 1100 m/s.

The invention has the advantages that:
the invention prepares the fully compact isotropic Ti-based all-metal energetic structural material with the density of about 7-10g/cm by strictly controlling the material components and the hot isostatic pressing process parameters, especially under the coupling action of isostatic pressure and temperature 3 The high-density components are uniformly distributed in the Ti matrix and are tightly combined with the matrix, so that the high-density component has excellent mechanical properties and good ignition property under impact conditions; the method has a wide speed application range, and is particularly suitable for application scenes with the landing speed below 1100m/s and above 1800 m/s; meanwhile, the preparation flow is simple and efficient, and is beneficial to realizing engineering preparation.

Comparative example 1
Compared with example 1, the difference is that: the sintering temperature of the hot isostatic pressing was 1000 ℃.
As a result, the Ti and Ta are obviously diffused, the fusion process of the Ti and Ta is completely completed, and the pure Ti area and the pure Ta area disappear to form the Ti-Ta alloy.
Comparative example 2
Compared with example 1, the difference is that: the sintering time of the hot isostatic pressing is 3.5h.
As a result, significant diffusion between Ti and Ta occurs, leaving only a very small amount of pure Ta regions in the composite, which have disappeared and completely converted into Ti-Ta solid solution.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
