Description
Technical field
The present invention relates to the amorphous magnetic material field, particularly relate to a kind of preparation method who has the bulk amorphous alloys of good mechanical property and high-magnetostriction concurrently.
Background technology
When magnetized state changed in magnetic field, ferromagnetic and ferrimagnetic material caused size or the small variation of volume, and this phenomenon is called magnetostriction.The size of magnetostrictive effect is represented with magnetostriction coefficient λ.Its value is λ=δ l/l, and l and δ l are the original length of magnet and the change of magnetization back length.Traditional magnetostriction materials are Ni and Fe base alloy, and the saturation magnetostriction coefficient lambda s of this metalloid and alloy is (± 30～70) * 10
-6, because the λ of this class material is too little, so use range is restricted.At the beginning of the sixties, people find that promptly rare earth element (R) has the magnetic of many uniquenesses.For example, the orbital momentum of heavy rare earths atom and spin angular momentum are all big, and are arranged in parallel, so each atomic magnetic moment is 9 μ
B～10 μ
B, and Ni and Fe have only 0.6 μ
BWith 2.2 μ
B1963, people such as Legvold measured Tb (terbium) and Dy (dysprosium) at low temperatures along the magnetostriction of basal plane, and the magnetostriction value of finding these basal planes is 100～1000 times of traditional magnetostriction materials magnetostriction value, and this makes magnetostriction materials breakthrough occur.The eighties in 20th century, people such as U.S. Clark find, TbFe
2, DyFe
2At room temperature has very big magnetostriction coefficient Deng the binary rare-earth iron cpd.TbFe at room temperature for example
2Magnetostriction coefficient λ
sBe 1800ppm, DyFe
2Magnetostriction coefficient λ
sBe 430ppm, they have higher magnetostriction coefficient at low temperatures.But saturation magnetic field is too high, does not have practical value.Further developed the ternary RE iron cpd afterwards, their magnetocrystalline anisotropy can compensate or cancel each other, and makes this (R
1R
2) Fe
2The type compound just can obtain very big magnetostriction coefficient in room temperature after the match with low.Tb for example
0.27Dy
0.73Fe
2Magnetostriction coefficient can reach 1500-2000ppm.Because the magnetostriction coefficient of this material is bigger 50 times than the basic alloy of Ni, than the big 5-25 of piezoelectric ceramics doubly, so be called giant magnetostriction material or giant magnetostrictive material.
The high-magnetostriction alloy material mainly is that Tb-Dy-Fe is main crystal alloy at present, though this alloy magnetostriction coefficient can reach more than the 1000-2000ppm, fragility is big, mechanical property is relatively poor, limited its widespread use, and needed a large amount of rare earth materials that use, cost is higher.Amorphous alloy has that the atomic arrangement long-range is unordered, the special microtexture of short range order, thereby has the intensity height, and fracture toughness property is good, the resistivity height, and superior machinery, physics and chemical property such as erosion resistance is good, application prospect is extensive.The machinery that non-crystaline amorphous metal is good, physics and chemical property and high-magnetostriction performance combine, and are the problem that crystal alloy exists in the hope of solving present high-magnetostriction Tb-Dy-Fe.At present, for traditional noncrystal membrane of methods such as sputter, fast quenching preparation, the magnetostriction performance of strip, existing several studies report, in only research report, Inoue group finds, Fe-Co-Ln-B (Ln=Sm or Tb) is that metallic glass has advantages of higher stability and saturation magnetostriction coefficient lambda s, has good tensile strength, bending strength, hardness and Young's modulus simultaneously.Fe
