Description
Technical field
The present invention relates to consumer electronics product, accurate device (such as robot), medical instrument, space flight and aviation application necks
The material of the high-mechanical property in domain, more particularly to the superhigh intensity Zirconium base non-crystalline composite material of a kind of high tenacity and its preparation side
Method.
Background technology
Non-crystaline amorphous metal is gained the name because it has apparent structure to distinguish with common crystalline material.General material is with crystal
Form exists, and the characteristic of amorphous is longrange disorder (shortrange order), metastable state (certain temperature crystallization), object to a certain extent
Manage characteristic isotropism, no definite fusing point, there is glass transition temperature point etc..Have simultaneously with common glass because of it similar
Structure, with solid-state, metal, the characteristic of glass, also referred to as glassy metal (Metallic Glass).Due to its maximum knot
Structure feature is exactly no grain structure, is directly uniformly distributed by atom is random, is keyed by metal between atom.Due to not having
There is grain structure, also just there is no the features such as the defects of crystal boundary and lattice period translational symmetry, therefore possesses traditional crystalline state and close
The excellent properties that golden material does not have, such as high mechanical properties, high rigidity, low elastic modulus, high-wearing feature, high anti-corrosion capability, with
And excellent soft magnet performance.This internal structure of non-crystaline amorphous metal is formed by super be quenched and solidified of the master alloy melted, former
Son has little time in process of setting by periodic arrangement, therefore forms the non-crystalline state of longrange disorder.After non-crystaline amorphous metal is found, inhale
The research and discovery of the decades of scientific research personnel is drawn, it has now been found that such as Zr bases, Cu bases, Al bases, Fe bases, Pd bases, Ni
The non-crystaline amorphous metal system of the systems such as base, Ti bases, Mg bases, rare-earth-based.
It is wherein notable with Zr base block amorphous alloy investigation of materials achievements, although Zr base noncrystal alloys are in the industry
High using restricting for the practical factor still applied by various aspects, such as cost of material, process conditions are harsh, and post-processing processing is again
It is miscellaneous etc..Wherein it is that non-crystaline amorphous metal does not have plasticity using maximum restraining factors, thus market application feedback is always to hesitate not
Before.So the toughness for improving non-crystaline amorphous metal becomes the active demand that this material is used for volume production.
It adds the second phase and prepares one kind that amorphous composite material is improvement non-crystaline amorphous metal toughness method, but additional phase and amorphous
Often there are problems that between matrix in conjunction with (wetability) so that the second phase and noncrystal substrate boundary strength are relatively low.In addition, additional phase
Addition generally requires larger volume score (being more than 40%) and can be only achieved toughening effect, thus it is uneven to easily cause additional distributed mutually
The problem of.Since the shape of additional phase is different, for threadiness, the second phase of sheet and three-dimensional framework shape, generally require to lead to
It crosses the methods of infiltration or hot pressing and prepares amorphous composite material, be not suitable for industrial production.Therefore, micro- addition of the second phase of graininess at
For the research emphasis of industrial production amorphous composite material.
