Definitions

  • the invention relates to a method for producing a powdery amorphous material, in which at least two powdery, at least partially crystalline, starting components are mechanically alloyed by means of a grinding process.
  • a method for producing an amorphous alloy is e.g. in the publication "Applied Physics Letters", Vol. 43, No. 1, 1.12.1983, pages 1017 to 1019.
  • Such amorphous alloys have a glass-like, amorphous structure instead of a crystalline one and have a number of extraordinary properties or combinations of properties, e.g. high wear or corrosion resistance, high hardness and tensile strength with good ductility as well as special magnetic properties.
  • microcrystalline materials with interesting properties can be produced (see e.g. DE-PS 28 34 425).
  • a process which has been known for a long time for the industrial production of new materials is the so-called "mechanical alloying" (cf. for example "Metallurgical Transactions", vol. 5, August 1974, pages 1929 to 1934, or "Scientific American", vol. 234, 1976, Pages 40 to 48).
  • powders of the starting elements or compounds of the desired alloy are ground together in a ball mill to form a mixed powder.
  • the grinding process is carried out until a homogeneous alloy of the components involved has formed.
  • the object of the present invention is now to design the method mentioned at the outset such that it can also be used to produce amorphous metal-metalloid systems which contain boron as the metalloid using the method of mechanical alloying.
  • this object is achieved by a powdered boron component made from elemental boron or from a boron compound or alloy is added to the powders from the starting components, this powder mixture is then subjected to the grinding process, an amorphous alloy component being formed from the starting components with fine or boron component particles incorporated or attached, and - That finally the resulting mixed powder of an annealing treatment below the crystallization temperature of the amorphous alloy component to diffuse the boron into the amorphous alloy component is exposed.
  • the invention is based on the known fact that the application of the mechanical alloying method in a known manner does not lead to success when using boron powders. It has been shown that boron cannot be alloyed mechanically due to its great hardness. The advantages associated with the invention can thus be seen in particular in that, despite these difficulties, it is possible to produce amorphous materials from special metal-metalloid systems, it also being possible to add boron powder to the powdery starting components and to use the method of mechanical alloying .
  • the metal-metalloid systems stand out compared to metal-metal systems e.g. by a much higher hardness, but also by their special magnetic and corrosive properties, so that they are of particular importance with regard to their technical applications.
  • M1 and M2 can generally be the powdered starting components in elemental form or in the form of alloys or compounds, the alloy M1, M2 can be obtained by the known mechanical alloying in amorphous form. M1 and M2 can in particular be transition metals such as Fe and Zr. Accordingly, a metallic glass is an exemplary embodiment made from a ternary alloy FeZrB.
  • amorphous powder from this alloy powders of the two starting components Fe and Zr and B powder together with hardened steel balls are first placed in a suitable grinding bowl, the ratio of the three powder types of this powder mixture being determined by the predetermined resulting atomic concentration of the powder to be produced from these powders Material is determined.
  • proportions (in atomic%) of the three components with 20 ⁇ x ⁇ 80 and with 4 ⁇ y ⁇ 30 are advantageously chosen.
  • a weight ratio of the three elementary powders can be provided which corresponds to Fe60Zr260B20 after alloying.
  • the size of the individual powders can be arbitrary; however, a similar size distribution of the two starting components involved is expedient in a range between 5 ⁇ m and 1 mm, preferably between 50 ⁇ m and 0.5 mm.
  • the B powder should be as fine as possible, advantageously a size of the powder particles below 10 ⁇ m, preferably below 1 ⁇ m. This can be largely amorphous B powder.
  • the three powders with the corresponding powder particle sizes are placed in a planetary ball mill (Fritsch brand: type "Pulverisette-5"), the steel balls of which, for example, have a diameter of 100 mm.
  • the grinding intensity can be influenced as desired with a variation of the ball diameter and the number of balls.
  • the grinding speed and the ratio of the steel balls to the amount of powder are further parameters which determine the grinding time required for amorphization.
  • the grinding container made of steel is placed under the mill Shielding gas, for example under argon, is kept and only opened again after the grinding process has ended.
  • finely layered powder grains are formed, which consist of Fe and Zr layers.
  • the B particles are embedded both at the Fe / Zr interfaces and in the elemental metals.
  • this layer structure becomes finer and finer until amorphous FeZr is present at the end of the grinding process after about 10 to 30 hours, in or on the powder particles of which B-particles are incorporated or attached.
  • the individual powder particles of the resulting mixed powder have a diameter of approximately 10 to 200 ⁇ m.
  • the amorphous FeZr material thus formed which is an alloy component of the ternary alloy to be produced, has good thermal stability, so that annealing at temperatures up to 600 ° C. does not lead to crystallization. Accordingly, the mixed powder thus produced is subjected to an annealing treatment below the crystallization temperature of the amorphous alloy component FeZr from the two starting components Fe and Zr for a few hours. After about 4 hours at 600 ° C, the B atoms have diffused into the amorphous FeZr, whereby amorphous Fe60Zr20B20 has formed. The amorphicity of this powder formed in this way can be demonstrated by X-ray examinations.
  • the powder of a metal-metalloid system produced in accordance with the invention in this way can then be further processed in a known manner to form a body or workpiece with the desired shape and dimension by compacting and, if appropriate, in further shaping steps.
  • This body has the characteristics that are characteristic of the amorphous material such as great strength at high temperatures.
  • the method according to the invention explained on the basis of the exemplary embodiment described above is limited to alloys which consist of three or more components or elements. At least two of the metallic components must be able to be amorphized by mechanical alloying.
  • the one starting component M1 should be a late transition metal such as Fe, Ni, Co, Cu, Au, Re, Cr, Mn and the second starting component M2 an early transition metal such as Zr, Ti, Hf, W, Nb, V, Mo or a rare earth metal or an actinide metal.
  • the boron provided for the process according to the invention does not always have to be provided in elementary form, but can also be partially replaced by another metalloid such as Si, P, C, Ge, if necessary.
  • the metalloid components are advantageously added in elemental form, and the boron can also be in amorphous form. In special cases, however, these elements can also be in the form of alloys or compounds such as add Fe2B or FeB as intermetallic phases.
