Description
Technical field
The present invention relates to a kind of methods of combustion reaction high―temperature nuclei NiMnGa Magnetic Memory alloy.
Background technique
Magnetically driven shape memory alloy has both response frequency height and exports the advantages of should becoming larger, in recent years by height weight
Depending on.Magnetic driving shape memory effect is had found in many alloys at present, specifically includes that Ni-Mn-Ga, Ni-Fe-Ga, Fe-Pd,
Fe-Pt, Ni-Mn-Al, Co-Ni-Ga, Co-Ni-Al and Ni-Mn-X (X=In, Sn, Sb) alloy etc..Wherein Ni-Mn-Ga is
It was found that the earliest and maximum magnetically driven shape memory alloy of application potential.
1996, Ullakko et al. was for the first time in Ni2The reversible strain that about 0.2% is obtained in MnGa monocrystalline, is pulled open since then
The research prelude of magnetic driven memory alloy, has become the research hotspot in marmem field.Domestic and international researcher is successive
Carry out magnetic driven memory alloy research, designs and prepares in alloy, the life of martensitic traoformation, mechanical behavior, magnetism characteristic, magnetic strength is answered
Change and its micromechanism etc. have made great progress.Chinese Academy of Sciences's CAS Institute of Physics in free sample, (answer by no applied stress or pre-add
Power) Ni52Mn24Ga24In obtain up to 1.2% merely by the magnetic-field-induced strain of induced by magnetic field.2000, Murray et al. existed
Ni47.4Mn32.1Ga20.55.7% magnetic-field-induced strain is obtained in monotropic body 5M martensite.2002, Sozinov et al. was having
There is the Ni of 7M martensitic structure48.8Mn29.7Ga21.5In monocrystalline, under 1T magnetic fields, the magnetic strength life for obtaining up to 9.5% is answered
Become, this is presently found maximum magnetic-field-induced strain.But when the preparation of Ni-Mn-Ga monocrystal material as caused by the effect of segregation
Component segregation, it is difficult to the uniform monocrystal material of large scale ingredient is obtained, and quality repeatability and stability are poor, it is at high cost.For this purpose,
People have invested polycrystalline Ni-Mn-Ga alloy for sight is studied.Ullakko et al. is in Ni49.6Mn28.4Ga22It is obtained in polycrystalline alloy
0.3% magnetic-field-induced strain, and the martensite of preferred orientation is obtained with the method for thermomechanical cycle, magnetic-field-induced strain is mentioned
Up to 4%.The study found that Ni-Mn-Ga alloy brittleness is larger, polycrystalline is more crisp than monocrystalline, has taken a variety of method for toughening,
Including addition Fe and rare earth element and powder metallurgy refinement crystal grain etc., Ni-Mn-Ga polycrystalline brittleness is improved.Wang
Et al. made under the conditions of operating pressure 80MPa, sintering temperature 1173K, sintering time 600s using discharge plasma sintering technique
For Ni2MnGa alloy, compression failure strain is up to 24%, much higher than the identical component alloy (closely having 8%) of fusion casting preparation.
In short, driving memorial alloy, the research of especially Ni-Mn-Ga alloy achieves considerable by the effort in more than 20 years
Progress, but there are still one to restrict its development and application critical issue-polycrystalline brittleness problems.Therefore, exploring improves Ni-
The polycrystalline brittleness of Mn-Ga alloy is one of important development direction and the research emphasis in magnetic driven memory alloy field.
Ni-Mn-Ga alloy brittleness is big, and machining property is poor, in typically along brilliant crisp after being broken under stress
Property fracture.View more consistent for intrinsic brittleness at present is: due to the atomic size of component alloy, chemical valence and other
Difference in relation to chemical property and be formed about uneven environment in crystal boundary, caused by keeping crystal boundary binding force lower.Meanwhile
This ordered intermetallic compound ordering energy with higher, the movement of crystal boundary atom is smaller, so that the atom of grain boundaries can be considered
The atomic arrangement of crystal boundary side or the atomic arrangement for belonging to the other side, columnar voids caused by the mispairing of this crystal boundary two sides cause
The brittleness of crystal boundary；In addition, unit-cell volume is larger so that dislocation motion Bai Shi vector becomes larger, independent slip-system is few, and crystal boundary
Special construction cause sliding not easily pass through crystal boundary and alloy have it is intrinsic along brilliant brittleness the reason of.Domestic and foreign scholars pass through big
Measuring work improves the plasticity of Ni-Mn-Ga alloy, improves its toughness, but not yet explore better solution.
