Description

A kind of iron base amorphous magnetically-soft alloy and preparation method thereof
Technical field
The invention belongs to magnetic functional material technical field more particularly to a kind of iron base amorphous magnetically-soft alloy and its preparation sides Method.
Background technique
Iron base amorphous magnetically-soft alloy has excellent magnetic performance (such as: high saturated magnetic induction, high magnetic permeability and low magnetic Damage), high resistivity and the advantages that high rigidity, it has also become one of materialogy and the emphasis of physics area research.Currently, Fe base is non- Brilliant magnetically soft alloy is in fields such as aerospace, power electronics, motors using very extensive.In distribution transformer field, it is used The no-load loss and no-load current of transformer are reduced in substitution silicon steel sheet.Fe-based amorphous band is used to manufacture supermarket and library The sensor magnetic stripe label of burglary-resisting system.In consumer electronic device field, it can be substantially reduced power volume, improve device efficiency, Increase anti-interference ability.Fe-based amorphous alloy energy-saving consumption-reducing is had excellent performance, and is a ideal energy-saving and environment friendly material, is expected to It substitutes the conventional soft magnetic materials such as silicon steel sheet, permalloy and is widely used in transformer, mutual inductor, disk memory and motor The industrial circles such as iron core.With China's rapid development of economy, the demand to electric power increasingly increases, and becomes to high-efficiency and energy-saving type amorphous The demand of depressor is very huge.Therefore, there is an urgent need to research and develop the novel Fe base noncrystal alloy with Good All-around Property, this gesture The exploitation and application of entire Fe base amorphous will be favorably pushed, there is important social effect and economic benefits.
It is numerous since Duwez professor in 1967 reports the first Fe base amorphous soft-magnetic alloy in Fe-P-C system Scientist has paid a large amount of effort during preparing new iron-based amorphous soft-magnetic alloy.1969, Pond and Maddin The continuous amorphous ribbon with certain length is prepared, to create condition for large-scale production amorphous alloy.1988, Yoshizawa etc. has developed Finemet type (Fe-Cu-Nb-Si-B) nano-crystal soft magnetic alloy, which has both Fe-based amorphous The characteristics of high saturated magnetic induction of the high magnetic strength of alloy and cobalt base amorphous alloy, high magnetic permeability and low iron loss.At the same time, Suzuki etc. is that Nanoperm type nano-crystal soft magnetic alloy is had developed in alloy in Fe-M-B (M=Zr, Hf, Nb).Currently, The research and development of FeNbBCu system amorphous soft-magnetic alloy have become the emphasis of Fe base amorphous area research.Cu element is added with Following advantage: (1) Cu and Fe has biggish positive enthalpy of mixing (+13 kJ/mol), and (2) reduce the distance of Fe-Fe atom pair, (3) The appropriate addition of Cu can hinder electron motion in alloy, improve resistance alloys rate, reduce eddy-current loss, and the addition of (4) Cu element is led Cause the big binding force between alloy constituent element, atom packing density height, diffusion coefficient low.Xue Lin substitutes Fe element by Cu and is prepared into To Fe84-xNb2B14CuxAmorphous alloy, the alloy do not have glass transition phase, crystallization initial temperature in temperature-rise periodT x1It is small In 698 K.Parsons etc. develops the FeNbBCu amorphous alloy at the low end B rich Fe, and crystallization initial temperature is about 650 K.
