Description
Technical field
The present invention relates to electronic material technology.
Background technology
Get into after 21 century, various countries are more deep for the research of stealthy technique, developed so far more than ten kind of absorbing material material.Utilize radar absorbing (RAM) can reduce the RCS of target.The effect of microwave absorption is even more important; All the aircraft of use matrix material seldom; Must apply microwave absorbing material keeping stealthy requirement in parts such as aircraft hardware, passenger cabin, radar modules, and these parts are very high to the microwave absorption performance requriements, in addition in the repacking of existing weapons; Apply microwave and inhale material in construction with safeguard because of having great convenience and low expense has remarkable advantages; And owing to combined microwave absorption, aircraft can more be considered aerodynamic configuration when research and development, to improve the operation handiness of aircraft.Except military aspect; Along with further developing of electronic communication and various microwave electrical equipment; Various electronic apparatus application increasing, electromagenetic wave radiation has become a kind of new social effects of pollution, the EMI that electromagenetic wave radiation causes; Not only can influence the normal operation of various electronicss, and harm also arranged healthy.Therefore absorbing material has also obtained at aspects such as information propagation, electron device, microwave protections to use widely.Fe base soft magnetic materials is high because of its magnetic permeability in microwave absorption, and loss is little, and good stability is so be studied and use widely.But now widely used most of Fe base soft magnetic materials is difficult to realize reducing the problem of anisotropy field.
And the FeNi permalloy has low anisotropy field; Thereby has very big advantage for improving magnetic permeability lifting absorbing property; And the FeNi permalloy has this excellent soft magnetic performance of very high magnetic permeability under low-intensity magnetic field, thereby develops into use field one of non-retentive alloy the most widely.But the FeNi alloy will obtain low anisotropy field need be realized under the condition of chilling, is difficult to obtain the FeNi permalloy of high magnetic permeability under the general condition.But add after the proper C r element, can suppress the formation of the non magnetic phase of Ni3Fe, thereby reduce anisotropy field, improve magnetic permeability; And need under the condition of chilling, just can not obtain the FeNiCr alloy of excellent soft magnetic performance yet, replace expensive Ni to have very big economic worth and market application foreground yet with cheap Cr.
Summary of the invention
Technical problem to be solved by this invention is that a kind of excellent flaky nanocrystalline magnetic micro-powder of excellent performance is provided.
The technical scheme that the present invention solve the technical problem employing is, a kind of Fe-Ni-Cr non-retentive alloy is characterized in that, by weight percentage, component is: Fe:52%~63%, Ni:36%, Cr:1%~12%.
More specifically, each component is: Fe:60%, Ni:36%, Cr:4%.
The preparation method of described Fe-Ni-Cr non-retentive alloy comprises the steps:
1) according to the weight percent of each component, gets following raw material respectively: iron powder, nickel powder and chromium powder;
2) be configured to mixed powder according to weight percent, the adition process control agent, ball milling obtains the Fe-Ni-Cr powdered alloy.
Said process control agent is an absolute ethyl alcohol; Adopt planetary ball mill, rotating speed is 300r/min; Ball is the zirconium ball in the ball grinder, and sphere diameter is 12mm; The ball that adds, the weight ratio of material and absolute ethyl alcohol is a ball: material: absolute ethyl alcohol=6:1:1.6.
Ferrous powder granules degree 60~100 μ m, purity >=98%; Nickel powder granularity 3~6 μ m, purity>99%; Chromium powder granularity 80~120 μ m, purity >=99.9%.
The invention has the beneficial effects as follows that it is simple that the present invention prepares Fe-Ni-Cr nano soft magnetic alloy powder technology, obtains excellent flaky nanocrystalline magnetic micro-powder easily.Like Fig. 5, Fig. 6 and shown in Figure 7 can access good soft magnetic performances such as the saturation magnetization that is higher than in the past and high magnetic permeability, obtains the absorbing property more excellent than FeNi two component system alloy.
The specific saturation magnetization that adopts vibrating sample magnetometer test micro mist and coercive force also are pressed into the coaxial composite sample of internal diameter 3mm, external diameter 7mm after with magnetic and paraffin uniform mixing in the ratio of 3:1.Adopt its magnetic spectrum of Agilent 8720ET Microwave Net vector analysis appearance test, shown in accompanying drawing in 500MHz~18GHz range of frequency.
