The technical features in the technical scheme provided by the invention are further and clearly described below in combination with the specific embodiments, and the protection scope is not limited.
The words "preferred," "more preferred," and the like in the present disclosure refer to embodiments of the present disclosure that may provide certain benefits in some instances. However, other embodiments may be preferred under the same or other circumstances. Furthermore, the recitation of one or more preferred embodiments does not imply that other embodiments are not useful, nor is it intended to exclude other embodiments from the scope of the invention.
When a range of values is disclosed herein, the range is considered to be continuous and includes both the minimum and maximum values for the range, as well as each value between such minimum and maximum values. Further, when a range refers to an integer, each integer between the minimum and maximum values of the range is included. Further, when multiple range description features or characteristics are provided, the ranges may be combined.

Exemplary subranges from 1 to 10 include, but are not limited to, 1 to 6.1, 3.5 to 7.8, 5.5 to 10, and the like.
In order to solve the problems, a first aspect of the present invention provides a fishhook comprising the following components in parts by weight: 60-80 parts of zirconium, 5-12 parts of carbon, 3-8 parts of copper, 5-10 parts of titanium, 3-8 parts of nickel and 0.2-0.5 part of aluminum.
In a preferred embodiment, the composition comprises the following components in parts by weight: 64 to 70 parts of zirconium, 8 to 11 parts of carbon, 5 to 7 parts of copper, 6 to 8 parts of titanium, 4 to 5 parts of nickel and 0.3 to 0.4 part of aluminum.
In a preferred embodiment, the composition further comprises the following components in parts by weight: 0.5 to 3 parts of hafnium and 0.3 to 0.5 part of arsenic.
In a preferred embodiment, the composition further comprises the following components in parts by weight: 0.3 to 0.5 part of strontium and 0.1 to 0.3 part of iron.
In a preferred embodiment, the weight ratio of zirconium to titanium is 1 (0.05-0.15).
In a preferred embodiment, the weight ratio of iron to nickel is 1 (20-30).
In a preferred embodiment, the weight ratio of copper to strontium is 1 (0.05-0.1).
The carbon can be completely dissolved, has a solid solution strengthening effect, can block dislocation movement, and meanwhile, crystal grains in an alloy structure remain finer, so that the strength and high-temperature creep property of the titanium alloy are obviously improved.
The copper can reduce the alpha-beta transformation temperature of the alloy, the solubility of the copper in alpha-Zr is less than 0.2%, and the formed intermetallic compound has Zr 2 The Cu phase improves the corrosion performance of the alloy, but the too high content of copper can influence the processing performance of the alloy and influence the yield of products, so the invention adds a small amount of strontium in the formula, has very obvious effect of refining grains, inhibits the growth of the grains, refines the grains, ensures that the grain size and the grain boundary become more uniform, and has outstanding gain effect on the precipitation of the second phase and increases the strength when the weight ratio of the copper to the strontium is 1 (0.05-0.1).
The titanium and zirconium can be infinitely dissolved to form a substitutional solid solution, and solute atoms blended into metal cause lattice distortion of the alloy, so that the resistance of dislocation movement is increased when the alloy is acted by external force. Solute atoms which are solid-dissolved near the dislocation can also play a role in dislocation pinning, and the strength and the tensile force of the alloy are improved. And when the weight ratio of the zirconium to the titanium is 1 (0.05-0.15), the effects are obvious.
The arsenic can enhance oxidation resistance and corrosion resistance, but excessive addition can generate tempering brittleness; the nickel element can improve the corrosion performance of the alloy without affecting the processing performance; nickel can lower the alpha-beta transformation temperature of the alloy, nickel and iron are added into the zirconium alloy as alloy elements, and when the weight ratio of the iron to the nickel is 1 (20-30), the nickel can optimize the processing performance and improve the mechanical performance of the zirconium alloy under the condition of improving the excellent corrosion resistance of the alloy. The method is mainly characterized in that the addition of the alloy elements nickel and iron increases the number of second phases formed by the alloy elements nickel and iron, so that the volume of the interface between the second phases and the matrix is increased, the alloy elements arsenic is prevented from being biased to an oxide/metal interface, in the corrosion process, the nickel and the iron are preferentially biased to the oxide/metal interface due to the higher diffusion speed of the nickel and the iron, and the grain boundary strength is increased due to the bias of the nickel and the iron, so that the corrosion resistance of a sample can be greatly improved.
The addition of the aluminum can reduce the density of the alloy, improve the recrystallization temperature, the strength and the (alpha+beta)/beta transformation point, and improve the oxidation resistance of the alloy. Meanwhile, aluminum can also improve the atomic binding force of the solid solution and increase the high-temperature strength of the alloy.
The hafnium of the present invention is an alpha-phase stabilizing element and can improve the strength and corrosion performance of the zirconium alloy, but the addition of a small amount of hafnium cannot achieve the required strength, so that it is required to be more than 0.5 parts by weight.
The second aspect of the invention provides a method for preparing a fishhook, comprising the steps of:
(1) Annealing each powder of zirconium, carbon, copper, titanium, nickel, aluminum, hafnium, arsenic, strontium and iron individually, classifying each powder by adopting a standard screen, and mixing the classified powder by adopting a mechanical dry mixing method;
(2) Granulating the mixed powder by adopting a vibrating screen or a roller granulator, pressing the prepared granules into green bodies in a molding press, and degreasing after further correcting the sharpness of the hook tips;
(3) And sintering the degreased green body at high temperature in an argon atmosphere, shaping the green body into a consistent shape, and polishing the hook tip to obtain the fishhook.
In a preferred embodiment, the vacuum degree of the high temperature sintering in the step (3) is 10 to 3Pa.
In a preferred embodiment, the high temperature sintering in step (3) is performed at a temperature of 1300 to 1700 ℃.
