Abstract
The present invention belongs to the technical field of amorphous and nano alloys, which is mainly used for manufacturing amorphous/amorphous nanostructural alloys. The alloy of the present invention comprises particular chemical components (weight percentage): 2 to 14% of Mo, 3 to 14% of Cr, 1 to 16% of Ni, 4 to 8% of P, 1 to 5% of Si, 1 to 4% of B, less than 0.5% of C, less than 1% of the sum of impurities, such as Mn, Ti, Al, S, O, etc. and the rest percentage of Fe. Because of the low critical cooling rate (10<3>k/s) of the alloy, amorphous alloy powder can be obtained by adopting a general rapid cooling method. Amorphous structures and nanon crystallization can be formed by appropriately controlling a cooling system, and the amorphous nanostructural alloy has higher crystallizing temperature (770 to 820K). The alloy material simultaneously has some amorphous and nanon crystal advantages, and manufactured alloy powder and products have the characteristics of high rigidity, corrosion resistance, abrasive resistance, etc. Because the alloy material has non-strict requirements for the contents of impurities, the alloy has the advantages of low raw material cost and convenient and simple preparation.
Description
Technical field:
The invention belongs to amorphous/amorphous Nanoalloy field, it is mainly used in makes or forms amorphous/amorphous nano structured alloy material and powder.
Background technology:
The application of amorphous material mainly is in electricity and magnetic fields now, and its favorable mechanical performance also well is not used.Chief reason is to form the amorphous alloy requirement than higher speed of cooling.So be difficult to form the non-crystalline material of bulk.Therefore major part all is to obtain amorphous surface by methods such as surface treatment or sprayings at present.
Present nano materials research has been penetrated into a lot of fields, and nano material has special electricity, magnetics and mechanical property because of its unique physical property.Mostly present application is to generate nanometer powder, microcosmic materials such as nano whisker, and by to material composition, generate the control of temperature schedule, in the matrix of non-crystalline material, generate nanophase and obtain the industrial application of amorphous nano structure material and few.
The purpose of this invention is to provide and a kind ofly can be used for producing thermally-stabilised good, corrosion-resistant, resistance to wear, high rigidity, having amorphous or amorphous nano structure, critical cooling velocity is lower than 10 when forming amorphous
3The alloy composition of K/s.
Summary of the invention:
The concrete chemical ingredients (weight %) of amorphous/amorphous nano structured alloy of the present invention is: Mo 2-14%; Cr 3-14%; Ni 1-6%; P 4-8%; Si 1-5%; B 1-4%; C＜0.5%; Mn, Ti, Al, S, O impurity summation are less than 1%; All the other are Fe.
Alloying constituent of the present invention mainly is from each dvielement role alloy, and amorphous, nanophase form and stability and design.The present invention is metal-metalloid alloy.Because at metal-metalloid (M-S) type alloy M
100-xS
xIn, the easiest formation non-crystalline state and the composition with high stability are to form near metal-metalloid eutectoid point composition, and the toughness that too high x value can the reduction amorphous alloy.Therefore, the composition proportion of amorphous/amorphous nano structured alloy of the present invention accounts for about 80% of alloy total amount to the design of the atomic percent of magnesium-yttrium-transition metal Fe, Cr, Ni, Mo, and the atomic percent of metalloid element B, Si, P, C etc. accounts for about 20% of alloy.According to above-mentioned design, can take into account amorphous stability, lower speed of cooling and higher toughness of material.By also extrapolating in the phasor, exist compound between multiple metal-metalloid in this composition range, and each composition of this alloy is near the polynary eutectic composition, this just makes the lowest total of the melting point Tm of alloy reduce, make the temperature head Δ Tg between it and the crystallization temperature Tg point dwindle, the easier formation non-crystalline state of alloy then, thus amorphous nano structured alloy can be obtained.It is lower by (＜10 that this also is that alloy of the present invention is in critical cooling velocity
3K/s) one of reason.In the constituent element of alloy of the present invention, Fe is a matrix element, and Ni, Cr, Mo have quite high solubleness therein, and the interpolation of Cr, Mo can also increase the viscosity of this alloy melt, large diameter Mo atom also can improve atom and rearrange the crystalline difficulty, thereby improves amorphous thermostability.The adding of long radius metalloid elements such as B, Si and P and magnesium-yttrium-transition metal form compound between metal-metalloid, macromolecular structure has also played the effect that improves amorphous stability, also can play simultaneously and hinder the grain growth effect, help the formation of amorphous nano structure.Owing to adopted the proportioning of above-mentioned alloying constituent, made the amorphous (accompanying drawing 1) or amorphous nano (accompanying drawing 2) structured material that prepare with this kind proportioning alloy have good hardness (Hv
0.1700-1000), thermostability (accompanying drawing 3), wear-resisting and anti-corrosion characteristic.

The chemical ingredients of four kinds of amorphous/amorphous nano structured alloys of table 1, weight %:
With the high frequency induction furnace melting of above-mentioned alloy, again alloy solution is cooled off powder process, obtain amorphous alloy powder, the X-ray diffraction curve of its certain stove powder is seen Fig. 1, from diffracting spectrum as can be seen, on resulting non-crystaline amorphous metal powder diffraction spectra, tangible debye line does not appear, but casual wide moral dispersion curve.
Alloy melt to identical component, suitably reduce speed of cooling powder process or the certain thermal treatment process of process, just can obtain its X-ray diffraction curve of amorphous nano structured alloy powder and see Fig. 2, from diffracting spectrum as can be seen, on resulting amorphous nano structured alloy powder diffraction spectra, overflowing the debye line that has occurred the not high broad of intensity in the wide moral dispersion curve.This explanation is dissolved with nano microcrystalline in amorphous phase.
Carry out Performance Detection to above-mentioned amorphous/amorphous nano structured alloy powder or to making amorphous/amorphous nano structured coating with this powder by heat spraying method, it the results are shown in Table 2.
