Description
Technical Field
The invention belongs to the technical field of composite material preparation, and particularly relates to a production method of an iron-nickel magnetic composite material doped with alumina particles.
Background
The iron-nickel alloy has many excellent properties, for example, the iron-nickel alloy with the nickel content of 30% -90% has good soft magnetic characteristics in a weak magnetic field and a medium magnetic field, has high magnetic permeability and low coercive force, is called permalloy, and the permalloy containing 78% of nickel has the highest initial magnetic permeability which is tens of times that of the traditional silicon steel material. The iron core material, the magnetic shielding material, the rectangular magnetic alloy and the thermomagnetic alloy permalloy are widely applied. When the mass fraction of nickel is 36%, the invar effect is produced, the expansion rate of the alloy is almost zero at room temperature, and the alloy shows good dimensional stability, so that the prepared iron-nickel soft magnetic material has the characteristics of low cost, high compressibility, high saturation magnetization and the like, can be used for manufacturing precise instruments, standard measuring tools, resonant cavities, wave guide tubes, variable capacitance blades, hard disk drives, shadow masks of kinescopes, thermosensitive transverse splicing bimetallic strips, laser elements and the like, and is widely applied to the fields of electronic industry, aerospace, precise instruments and the like.
For functional materials, only a single characteristic of the functional material in a certain aspect is concerned in the past, the requirement of scientific and technological development on the material cannot be met, the functional material is required to have certain mechanical bearing capacity in certain scenes, and for example, a nickel core ferromagnetic ring commonly used in the communication industry needs to have certain mechanical properties to maintain the shape and size of the nickel core ferromagnetic ring and support surrounding parts besides the functions of magnetic storage, signal transmission and the like. And if the addition of other elements is strictly controlled by the invar alloy, the internal structure of the alloy is a single austenite structure, so that the strength of the invar alloy is generally low, about 500MPa, the invar alloy is used as a material of some non-bearing parts for a long time, and the development of the structure-function integrated application potential of the invar alloy is limited by the low strength.
Although the traditional methods for reinforcing materials, such as solid solution strengthening, work hardening and the like, can improve the strength of the materials to a certain extent, the traditional methods are all based on cold and hot working processes with complex processes, the iron-nickel alloy is extremely sensitive to various macroscopic and microscopic stresses generated in the working process, and the traditional mechanical processing method is used for generating irreversible damage to the magnetic properties of the iron-nickel alloy, so that the magnetic induction strength and the magnetic permeability of the iron-nickel alloy are reduced, and the balance among the options of functions/structures is difficult.
Therefore, the invention tries to introduce the alumina particles into the iron-nickel alloy in a liquid phase mixing mode, and aims to improve the mechanical property of the iron-nickel alloy and widen the application of the iron-nickel alloy in the aspects of stressed structural members with certain requirements on material functions and the like by introducing the second phase which is dispersed and distributed. Alumina is a high temperature structural ceramic with high hardness, high wear resistance, high chemical stability, low cost, and wide application in industry. The aluminum oxide particles are distributed in the iron-nickel alloy, so that on one hand, the movement of dislocation in the alloy can be hindered, dislocation winding, plugging and the like are generated at the particles, the strength of the alloy is improved, and the aluminum oxide particles with fine and uniformly distributed particles can also play a role in dispersion strengthening; on the other hand, the alumina particles among the crystal grains can block the transmission of dislocation among different crystal grains, the mutual fusion and growth of alloy crystal grains are limited, the alloy crystal grains are enabled to be finer and more dispersed, and particularly the stable physical and chemical properties of the alumina at high temperature also enable the alloy to keep good dimensional stability at high temperature. The yield strength, tensile strength and plastic toughness of the iron-nickel alloy are improved while the unique magnetic properties of the iron-nickel alloy are maintained.
The method for preparing the iron-nickel magnetic composite material mainly comprises the following steps: mechanical alloying method, spray pyrolysis method, chemical method, etc. In publication No. CN108568529A, leichenolong et al mixes iron, nickel metal salt and precipitant in a solution at a certain ratio, precipitates, filters, dries, mechanically mixes with sodium chloride and alumina, and anneals and cools at a certain temperature and time to obtain iron-nickel alloy powder. In publication No. CN108726581B, Naciocong et al use spray pyrolysis method to make iron-nickel alloy melt obtained by electric furnace reduction smelting of nickel iron ore, refining desulfurization, blowing and impurity removal in converter, and then make it undergo the processes of ball-milling, screening and fluid-state oxidation roasting so as to obtain iron-nickel oxide. In publication No. CN110813296A, Hexuan et al uniformly mixed the precursors of zinc, nickel and iron and alkali in solution at a certain ratio, carried out hydrothermal reaction in a hydrothermal kettle, filtered, washed, dried, and reduced in a tube furnace to obtain the nano-porous iron-nickel alloy powder. The method is simple and feasible, but is not easy to realize industrial mass production.
