Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing.
It illustrates below and the present invention is described in more detail:
(1) Ni is prepared using high-energy mechanical ball milling method disclosed in patent (ZL200710071687.8)49.8Mn28.5Ga21.7
Alloying pellet obtains NiMnGa particle of the particle size less than 100 microns；
(2) atomization spherical shape Cu powder particles of the particle size less than 100 microns are selected；
(3) by NiMnGa particle and Cu powder particles, 1:4,3:7 and 1:1.5 carry out ingredient by volume, NiMnGa particle
It is 20%, 30% and 40% that volume content, which respectively corresponds, then using high speed vibration ball mill (abrading-ball is not added) by NiMnGa
Grain obtains mixed-powder with Cu powder particles mixing 30min；
(4) uniformly mixed powder is placed in mold, the sinter molding in discharge plasma sintering furnace, sintering pressure
For 40MPa, sintering temperature is 800 DEG C, and the sintered heat insulating time is that 5min takes sample after temperature drops to room temperature from mold
Out, NiMnGa particle/Cu composite material is obtained.Pure Cu bulk is prepared using identical sintering process parameter simultaneously.Composite material
Preparation flow is as shown in Figure 1.
(5) scanning electron microscopic observation NiMnGa particle/Cu composite material microscopic structure is utilized, as shown in Fig. 2, Fig. 2 (a),
(b), (c), (d) are respectively the microstructure picture of the composite material of pure Cu, 20%, 30%, 40%.It can be seen from the figure that sharp
The pure surface Cu with SPS sintering preparation is finer and close, basic without sintering hole.After adding NiMnGa particle, composite material table
Face is mainly by dark and light two kinds of organizational compositions, and as NiMnGa granule content increases, dark color tissue gradually increases.EDS energy
Spectrum test result shows that dark tissue is mainly the phase of reacting of NiMnGa and Cu, and light color tissue is Cu or NiMnGa, such as arrow in figure
Shown in head, therefore as the reaction product content that NiMnGa granule content increases NiMnGa and Cu gradually increases.In addition, from figure
As can be seen that compared with the composite material of pressureless sintering method preparation, NiMnGa particle/Cu of discharge plasma sintering process preparation
Quantity significantly reduces the defects of hole caused by sintering process in composite material.
(6) material phase analysis is carried out to NiMnGa particle/Cu composite material using X-ray diffractometer, as shown in figure 3, with
NiMnGa granule content increases, and the diffraction maximum of Cu matrix gradually weakens in composite material, only detects in 40% composite material
A small amount of NiMnGa diffraction maximum, this result side light, the crystal structure and Cu matrix phase of NiMnGa particle and Cu reaction product
Seemingly, when granule content is 40%, the single NiMnGa content in composite material is higher, thus it is observed that the diffraction of NiMnGa
Peak.
(7) bent using multi-parameter magnetics test system and test NiMnGa particle/Cu composite material ac magnetic susceptibility-temperature
Line, as shown in figure 4, apparent martensitic traoformation and Curie transition is not detected in 20% and 30% composite material, 40%
The Curie transition that NiMnGa is detected in composite material illustrates that the single NiMnGa content in 40% composite material is higher,
This is consistent with above-mentioned X-ray diffraction result.
(8) bent using universal electrical Material Testing Machine test NiMnGa particle/Cu composite material compression stress-strain
Line is not broken in compression process as shown in figure 5, the plasticity of fine copper is good, finally compresses flakiness.With NiMnGa
The addition of grain and content increase, and the compressive strength of composite material is gradually increased, but plasticity declines to a certain extent.In
Can be obtained in 40% composite material > compressive strength of 850MPa and > 30% breaking strain, show good comprehensive mechanics
Performance.
Recently, we are prepared for NiMnGa/Cu composite material using pressureless sintering method, and result of study shows NiMnGa
Grain can effectively strengthen Cu matrix, but due to not applying pressure in sintering process, lead to the sintering hole etc. in composite material
Defect is more, to reduce the plasticity of composite material.NiTi particle and Cu Particles dispersed are utilized into discharge plasma legal system
The result of study of standby composite material finds that discharge plasma is sintered (heating rate is fast, sintering time is short) can be sintered
Apply different pressures in journey, the deformation of Cu can be effectively facilitated, thus the defects of reducing the hole in sintered combined material.Cause
This, the present invention proposes to prepare NiMnGa particle/Cu composite material using discharge plasma sintering process, passes through Fast Sintering of pressurizeing
