All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.
Furthermore, the terms "long", "short", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention, but do not indicate or imply that the referred devices or elements must have the specific orientations, be configured to operate in the specific orientations, and thus are not to be construed as limitations of the present invention.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Example one
This example provides a composite core made by the core making method of example two, and the armor-piercing projectile made from the composite core has excellent penetration performance and can efficiently penetrate through an object.
Example two
The embodiment provides a method for preparing the core, which is used for preparing the composite core in the first embodiment and has the same functions and beneficial effects.
Referring to fig. 1, the method for preparing the bullet core comprises the following steps:
s10: providing a mold having a mold cavity, a pellet, chip or powder made of a high density material, and an amorphous filler or high entropy alloy made of an amorphous material;
s20: placing a plurality of pellets, chips or powder into a mold cavity;
s30: adding amorphous filler or high-entropy alloy into the die cavity, so that the amorphous filler fills gaps among the shots, fragments or powder;
s40: vacuumizing the die cavity and heating;
s50: and cooling to solidify the amorphous filler or the high-entropy alloy to obtain the composite elastic core.
When the armor piercing bullet impacts a target object, the energetic material generates sparks at the impact moment and releases a large amount of heat to melt the surface of the target object, and finally the penetrating effect is achieved.
Furthermore, amorphous filler or high-entropy alloy is added into the die, so that the molding of the composite bullet core can be realized, the density of the armor-piercing bullet can be increased, and the destructive power and the penetrating power of the armor-piercing bullet are improved.
Optionally, the die cavity is of a spherical structure, and the composite core is also of a spherical structure.
Specifically, the spherical structure can ensure that the composite bullet core uniformly heats in all directions during impact, and the uniformity of the penetrating power of all parts of the armor-piercing bullet is improved.
In this embodiment, the high-density material is an energetic material and/or depleted uranium, or the like.
Specifically, the energetic material and the depleted uranium have higher densities, and can release a large amount of heat when impact occurs, so that the armor piercing capability of the armor piercing bullet can be effectively improved.
Optionally, the amorphous material is an energetic material such as zirconium, copper, iron, chromium or lead, and further may be a high-entropy alloy composed of materials such as aluminum, cobalt, chromium, zirconium, iron, nickel, copper and titanium.
It is understood that zirconium and copper have better formability and are advantageous for producing spherical cores.
When an element or layer is referred to as being "on" … … "," engaged with "… …", "connected to" or "coupled to" another element or layer, it can be directly on, engaged with, connected to or coupled to the other element or layer, or intervening elements or layers may also be present. In contrast, when an element or layer is referred to as being "directly on … …," "directly engaged with … …," "directly connected to" or "directly coupled to" another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship of elements should be interpreted in a similar manner (e.g., "between … …" and "directly between … …", "adjacent" and "directly adjacent", etc.). As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region or section from another element, component, region or section. Unless clearly indicated by the context, use of terms such as the terms "first," "second," and other numerical values herein does not imply a sequence or order. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as "inner," "outer," "below," "under," "lower," "above," "upper," and the like, may be used herein for ease of description to describe a relationship between one element or feature and one or more other elements or features as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below … …" can encompass both an orientation of facing upward and downward. The device may be otherwise oriented, such as by rotation through 90 degrees or other orientations, and is explained with the spatially relative descriptors herein.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present 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 solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
