Abstract
The invention relates to the technical field of manufacturing of bulk amorphous alloy, in particular to low-cost bulk amorphous alloy. The chemical formula of the low-cost bulk amorphous alloy is Zra(Hf,Ti)bAlc(CuxNiy)d(Ag,Re)e(Li,Na,K,Si,Mg,Ca)fOg, wherein a, b, c, d, e, f and g are the percentage contents of corresponding atoms of all the elements in the amorphous alloy, 45<=a<=70, 5<=b<=10, 3<=c<=15, 20<=d<=40, 0<=e<=3, 0<=f<=10, 0.05<=g<=1 0.2<=x/y<=5, 0.1<=e+f<=10, and Re is one or more of rare earth elements. According to the low-cost bulk amorphous alloy, the sensitivity of a formula to the oxygen content is greatly reduced, so that the large bulk amorphous alloy suitable for industrial application can still be formed under the high oxygen content condition.
Description
Technical field
The present invention relates to block amorphous alloy manufacturing technology field, particularly relate to a kind of low cost block amorphous alloy.
Background technology
Zr base noncrystal alloy makes it have the performance of many excellences due to the singularity of its structure, as: high strength (>=1500MPa), high rigidity (about HRC50), high elastic limit (about 2%), excellent erosion resistance and liquid near-net forming etc., have important application prospect in fields such as consumer electronics, health care, aerospace and communications and transportation.
For Zr base noncrystal alloy, develop multiple alloying constituent at present, as the alloy system of the Zr-Ti-Cu-Ni-Be system of U.S.'s exploitation, Critical cooling speed reaches 1K/s, amorphous formation ability is strong, can manufacturing capacity strong, but due to the existence of toxic element Be element in this alloy system, restrict its widespread use.The Zr-Al-Ni-Cu alloy system of Japan's exploitation, its amorphous formation size can reach φ 30mm, but needed for this alloy system, preparation condition is harsher, needs high purity raw material and condition of high vacuum degree technology of preparing.
In the GFA of existing Zr base alloy and toughness alloy, oxygen level is responsive especially.Because zirconium and oxygen have very strong bonding force, easily generate zirconium white or zirconium/oxygen cluster in alloy melt, they can be used as the core of non-homogeneous nucleation, and the GFA of alloy is reduced, small crystallization simultaneously becomes tiny crack source in the alloy, and the toughness of alloy is also declined thereupon.Due under common laboratory or industrial process conditions, a certain amount of oxygen is inevitably introduced in Zr base noncrystal alloy, therefore must adopt expensive high-purity raw material and melting in production process, press casting procedure requires pumping high vacuum, vacuum tightness often requires 10
-2more than Pa even 10
-3pa, causes the reduction of amorphous GFA to prevent the rising of oxygen level in alloy.The protective atmosphere of high pure raw material (more than 99.9%) and harshness causes the preparation cost of Zr base noncrystal alloy very high, can not meet large-scale volume production.When adopting industrial raw material comparatively general on market, parts and the product of the amorphous structure with certain size can not be prepared again, the toughness of alloy also can be caused simultaneously to decline to a great extent, thus cause the finished product reliability to decline to a great extent, seriously constrain it and produce and application.
Summary of the invention
The technical problem to be solved in the present invention is: higher to the susceptibility of oxygen level in industrialization continuity production process in order to solve non-crystaline amorphous metal system in prior art, be difficult to the problem forming amorphous bulk, the invention provides a kind of low cost block amorphous alloy, considerably reduce the susceptibility of formula to oxygen level, under higher oxygen level, still can be formed block, can the bulk amorphous alloy of industrial applications.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of low cost block amorphous alloy, consisting of of described non-crystaline amorphous metal: Zr

As preferably, described Re is the combination of one or more and Y in La, Ce, Po, Ho, Er, Nd, Gd, Dy, Sc, Eu, Tm, Tb, Pr, Sm, Yb, Lu element.
Particularly, described Ti accounts for all atomic percentage concs and is not less than 5.
Particularly, the atom percentage content that described each element is corresponding in non-crystaline amorphous metal is respectively: 50≤a≤60,5≤b≤7,7≤c≤12,25≤d≤35,0.1≤e≤1.5,0.5≤f≤10,0.05≤g≤1.
The invention has the beneficial effects as follows: the invention provides a kind of low cost block amorphous alloy, considerably reduce the susceptibility of formula to oxygen level, under higher oxygen level, still the bulk amorphous alloy that limit amorphous is larger-size, toughness is comparatively excellent can be formed, and with low cost, be very applicable to suitability for industrialized production, Li is introduced in block amorphous alloy of the present invention, Na, K, Si, Mg, the elements such as Ca, the atomic size of these elements is little, be conducive to the accumulation of atom on microscopic pattern, effectively can suppress the crystallization of metal liquid in process of cooling, simultaneously in the molten state with the affinity of O atom higher than Zr, the low-density oxide compound of easy formation floats over molten metal surface, and decompose under vacuum atmosphere, thus fundamentally add the Forming ability of non-crystaline amorphous metal, thus it is more broad to make non-crystaline amorphous metal make required raw-material range of choice, and can under the condition not selecting high-purity raw material, there is good amorphous formation ability, reduce manufacturing condition simultaneously, greatly reduce production cost.
