Definitions

  • the present invention is related to products produced from Fe-based amorphous alloys (also called bulk metallic glass), and to the application of such products, in particular as magnetic cores.
  • Fe-based bulk metallic glass BMG
  • Fe-alloys used for this purpose, in comparison for example to Zr-based alloys.
  • a large number of elements are usually added to Fe in order to produce Fe-based BMG's.
  • 'bulk' we refer to three-dimensional bodies, wherein the smallest dimension is at least 0.3mm.
  • Fe-based amorphous materials generally have good soft magnetic properties, i.e. coercivity is very low and permeability shows large values.
  • the FeNbBSi-alloy is a known example in terms of these characteristics. It is known in the art to fabricate ribbons of these compositions and also to apply such ribbons for making magnetic cores.
  • the ribbons (20 ⁇ m) are wound to form a ring-shaped product.
  • Other techniques involve the cutting of "thick" ribbons (up to 50 ⁇ m) with a ring-shape and the stacking of them in order to form the thick ring-core. All these steps make the production of such magnetic cores more expensive.
  • T is currently no soft magnetic amorphous Fe-based material having a thickness higher than 300 ⁇ m with a high level of impurities (industrial ferroalloys used) and suitable for soft magnetic applications.
  • the present invention aims to provide an amorphous Fe-based alloy and a process for producing products made thereof, said alloy and products being producable from industrial base materials, whilst yielding an end product with soft magnetic properties and being suitable for low frequency applications.

  • the starting materials may comprise raw Fe-alloys used in the steel industry. These materials are introduced into a melting device, and heated up to a temperature higher than their melting temperature, preferably between 1300°C and 1600°C. In the case for example of the Fe 36 CO 36 Nb 4 B 19.2 Si 4.8 composition it is preferred to have a temperature higher than 1350°C.
  • the melting can be done under air or under a protective atmosphere, e.g. Ar.
  • the atmosphere is controlled by creating a vacuum in the melting chamber before introducing the starting materials.
  • a vacuum of at least 10 -1 bar, preferably at least 10 -2 bar is created inside the chamber in order to get a clean atmosphere.
  • an Ar-atmosphere can be used, for example at a pressure of 1 bar.
  • the material is kept in a molten state during a period of time, preferably between 100s and 300s, to promote homogenization (especially important for the dissolution of FeB). Then the molten material is cast into a mould, preferably a Cu-mould, and cooled down to form the product.

  • the amount of Mn in the Fe-alloys (starting materials) is preferably lower than 2% and more preferably lower than 1%.
  • the melting step can be performed in a levitation melter, e.g. a 100cc levitation melter.
  • a levitation melter is a cold crucible induction melter. It consists of a copper crucible cooled by a circulation of water and a coil system creating a varying magnetic field. This magnetic field creates Foucault currents in the conductive materials inside the crucible which have three effects : heating the metals in the crucible up to their melting point, stirring the molten alloy, thus homogenising it, and making the molten mass levitate.
  • levitation melting there is no contact between the molten alloy and the crucible, which can remain cold while the melt can stay clean.
  • the materials When a levitation melter of 100kW power is used for the realization of the process of the invention, it is preferred to melt the materials at a power of at least 25% of the total power and preferably in the range 25-50% of the total power.
  • the pressure in the melting chamber is preferably at least 1 atm.
  • the steps of the process as described above are used to form a master alloy. These steps are then followed by a further series of steps to form the final product, e.g. a ring core. It is important to have in the master alloy an O-level lower than 0.05 wt.% and it is preferred that this level is lower than 0.03 wt.%.
  • some impurities must not exceed certain values in the master alloy or final product : Ti, S and N.
  • the total amount of (Ti + S + N) must be lower than 0.2% and preferably lower than 0.1%.
  • other impurities might reach higher values, being beneficial for the glass forming ability. This is the case of Al, Ni, Cr, Cu, Mn, C and P.
  • This value can be fixed to 2% and preferably to 1%.
  • the further steps of producing the bulk metallic glass product from the master alloy can be done in a melting device, like an induction melting device or a levitation melting device.
  • An air atmosphere can be used although a controlled atmosphere or an atmosphere with low oxygen levels is preferable.
  • the BMG can be cast in rods of up to 4mm, but also in other shapes, like ring-cores.
  • the process to form the BMG-product from the master alloy preferably comprises the following steps :
  • Table 2 gives an example of the composition of starting materials used in the method of the invention (in wt.%).

  • the amorphicity of the obtained materials can be tested by means of different techniques.
  • DSC differential scanning calorimetry
  • XRD XRD
  • Differential scanning calorimetry gives the evolution of heat capacity of a sample when it is heated. The sample is heated along with a reference (an empty crucible) so that both always have similar temperatures, controlled with accuracy. The difference between the energies brought to the sample and reference to heat them up at the same rate is monitored and gives the difference of behaviour. Endothermic and exothermic transformations in the sample can be spotted because they happen when respectively more or less energy must be brought to it to keep the same heating rate. So changes in heat capacity indicate phase transitions such as crystallisation or even simple transformations like glass transition.
  • Figure 1 gives the DSC of an Fe 36 Co 36 Nb 4 B 19.2 Si 4.8 alloy produced according to the method of the invention.
  • a glass transition and a first crystallization peak are clearly visible on the figure (curve 1).
  • the curve 2 on the DSC curve has no visible glass transition and a very slight crystallisation peak at around 600. This means that the sample is not fully amorphous and contains only a very small amount of amorphous phase.
  • curve 2 it was detected that the oxygen of the master alloy was over the recommended limits, being higher than 300 ppm. For this reason it was not possible to produce a bulk metallic glass.
  • amorphous materials e.g. polymers, silica-based glasses
  • bulk metallic glass shows no peak of diffraction on an X-ray diffractogram but a broad halo. This is due to the lack of long-range order and crystallinity and to the presence of short range order.
  • the X-ray diffraction diagram of an amorphous sample with chemical composition Fe 36 CO 36 Nb 4 B 19.2 Si 4.8 produced according to the present invention is shown by figure 2 , where no Bragg peaks can be noticed, meaning that the sample is essentially amorphous.
  • Figure 3 shows the B-H loop of Fe 36 Co 36 Nb 4 B 19.2 Si 4.8 as measured by means of a Vibrating Sample Magnetometer (VSM). A saturation magnetization of 1.04T is measured together with a coercivity of 4.5A/m.
  • VSM Vibrating Sample Magnetometer
  • a hysteresis loop tracer was used to measure systematically the coercivity of the bulk metallic glass products produced according to the present invention.
  • Table 3 presents the results corresponding to two materials from the present invention and two comparative examples. The measurements were performed on 2 mm diameter rods of as-cast materials; no additional annealing treatments have been performed.
  • the bulk metallic glasses show very low values of coercivity, making these materials very suitable for soft magnetic applications.
  • the material is only partially amorphous the coercivity reaches very high values.
  • the O-content of the master alloy exceeded the limits of the present invention (>300ppm). For this reason it was not feasible to produce a bulk metallic glass with such master alloy.
  • the second comparative example corresponds to a bulk metallic glass product of the same composition but prepared with pure elements.
  • the amorphous materials produced by the present invention i.e. starting with standard Fe-alloys have magnetic properties similar to those of bulk metallic glass produced with high-purity elements.
