Abstract

The invention discloses a molding method for improving the room-temperature plasticity of a metal glass component. The method has key technology that two measures of a mold-filling narrow channel and large mold-filling pressure are utilized to provide a subcooled liquid with a large enough deformation ratio and a high rheological rate during a mold-filling process, so that highly-dispersed local micro-areas having significant differences of microstructures and properties are triggered to form in the component after molding. When serving a load, the component enables a high-density shear belt to be started, so that the plasticity is obviously improved and brittle failure is prevented. The method mainly comprises: leading a pulse large current in a metal glass blank to make the temperature of the metal glass blank quickly rise to a subcooled liquid phase region and to make the metal glass blank become a subcooled liquid and to be softened; under the function of the mold-filling pressure, making the subcooled liquid pass through a pre-made mold-filling narrow channel at a high speed and to be injected in a cavity module; and performing molding to obtain the metal glass component with required shape and size. The method is easy to operate, saved in energy and free of pollution, needs no vacuum condition, and is particularly suitable for producing a metal glass component with high plasticity requirement and complicated shape.

Description

A kind of forming method improving metal glass component temperature-room type plasticity
Technical field
The invention belongs to metal glass component and manufacture field shaping technique, particularly relate to a kind of raising metal glass component room temperature The forming method of plasticity.
Background technology
Metal glass (also known as non-crystaline amorphous metal) has the performance more excellent than conventional corresponding crystal alloy material, such as pole High intensity (close to theoretical value), good elastic performance (elastic limit is about 2%), good corrosion resistance, Flouride-resistani acid phesphatase energy Power and anti-wear performance etc., be that a class range of application constantly expands and the new function material of great potential and structural material.So And, one of bottleneck of restriction metal glass material range of application is its temperature-room type plasticity the lowest even plastic-less deformation ability.But, Metal glass material has brittleness at room temperature, easily forms crackle when applying external force and exceeding its yield strength and causes moment crushing Fracture, leaves serious potential safety hazard;Additionally, due to its relatively low thermal conductivity, higher hardness, the machining of metal glass Poor-performing, it is impossible to obtained the workpiece of accurate complicated shape by conventional mechanical processing technique, thus seriously constrain metal The engineer applied that glass material is actual.In order to reverse this situation, people have done lot of experiments and have worked and propose multiple Effective ways, are broadly divided into following two aspect:
On the one hand, in order to improve the temperature-room type plasticity of metal glass, researchers or take to introduce the second crystal and form amorphous/crystalline substance mutually Composite material, or by microalloying, change over distribution ratio and regulate and control alloying component, or use precompressed, cold rolling and shot-peening etc. Mechanically deform means are to methods such as the prefabricated small shear bands of metal glass material.Such as, Johnson seminar in 2000 (Physical Review Letters 84.13 (2000): 2901-2904) is first at Zr-Ti-Cu-Ni-Be non-crystaline amorphous metal In situ introduce Ti-Zr-Nb crystal the second phase on matrix, this crystal can not only stop mutually localization shear band Quick Extended, Promote the generation of more shear band, moreover it is possible to participate in energy dissipation and plastic deformation by producing the sliding of dislocation, thus improve whole The plasticity of individual material;2007, seminar of Wang Wei China of the Chinese Academy of Sciences (Science 315 (2007): 1385-1388) was by adjusting Zr-Cu-Al-Ni block amorphous alloy composition, introduces the soft or hard district of microinhomogeneities micro-nano-scale in other words, successfully prepares Go out the compression plasticity superplastic alloy system more than 150%;2010, M.H. Lee et al. (Scripta Materialia 62.9 (2010): 678-681) to Zr44Ti11Cu9.8Ni10.2Be25And Zr55Ti5Al10Cu20Bulk amorphous alloy carries out the coldest Roll, prefabricated a large amount of micro-nano-scale shear bands, thus obtain bigger temperature-room type plasticity.
Regrettably, relevant with disordered state structure lower thermal conductivity and high rigidity are still present in these gold strengthening plasticity Belong in glass material so that they are still difficult to be made into required engineering component by conventional mach mode, thus Weaken the using value of its reality.
On the other hand, in order to obtain the metal glass component of desired shape, people generally use thermoplastic forming processes, First metal glass is heated to its supercooling liquid phase region with certain speed so that it is show low viscosity rheological behaviour, one Determine under load effect, be pressed in the copper mold chamber being pre-designed, obtain the metal glass part of required form after cooling.Should Method can mold tens nanometers to centimeter-scale, different metal glass part, such as: Jan Schroers etc. People (Nature 457.7231 (2009): 868-872) success imprints out diameter on porous alumina membrane and is about 13 nm Metal glass rod, and on the silicon chip etched in advance, produce diameter be about the amorphous gear of 300 μm;William L. Johnson et al. (Scripta Materialia 60.3 (2009): 160-163) is by Ф 19 х 20 mm's Zr35Ti30Be27.5Cu7.5Bulk amorphous alloy rod is pressed into 2 х 10 х 60 mm lath-shapeds exactly.
But, conventional heating means can not provide the rate of heat addition (generally less than 1.67 DEG C/s) faster, adds Thermoplastic forming processes used relatively low strain rate (generally less than 10 in the past-1 s-1) so that whole forming process is taken Between longer, this results in bulk amorphous alloy generation major structural relaxation, even crystallization, causes hot-short phenomenon, causes its temperature-room type plasticity And fracture strength substantially reduces.As far back as 2007, Takamasa Yoshikawa et al. (Key Engineering Materials Vols. 340-341 (2007) pp 113-118) by bulk amorphous alloy Zr55Cu30Al10Ni5Carry out thermoplastic Property molding research, find: after experiencing 676 K thermoplastic moldings, this fast body amorphous room temperature compressed rupture strength is from as cast condition 1500 MPa is down to 200 MPa suddenly, even if under lower temperature 667 K, its fracture strength also reduces 100 MPa, shows conventional thermoplastic Property forming method has the negative effect can not ignore to bulk amorphous alloy mechanical property.
It is important to note that 2011, William L. Johnson et al. (Science 332.6031 (2011): 828-833) to Pd43Cu27Ni10P20Bulk amorphous alloy passes to big pulse current, and the most time-consuming 3 ms are the most successfully heated To supercooling liquid phase region (~ 720 K), 20 MPa side crops industry are used just to be compressed into circular amorphous component, whole forming process Only used time 40 ms.This unusual heating means have more than 1 х 105The rate of heat addition of K/s, substantially reduces into The type time so that hot-short phenomenon is avoided, remain original as cast condition amorphous fracture strength, but, how to improve bulk amorphous alloy The brittleness at room temperature of component intrinsic does not has been resolved in the above-mentioned methods.
In sum, how to strengthen metal glass temperature-room type plasticity and to be effectively made into engineering component be to realize metal glass Shifting to an earlier date of the real engineer applied of glass, is also the big target of Study on Metallic Glass two.Although research both at home and abroad and invention be not achieved with Few progress and positive effect, but realize this two big target the most simultaneously, it is possible to simply and efficiently obtain high-ductility metal glass structure Part remains an outstanding question, is badly in need of method and technical innovation.
