The present invention provides a metal-based thermoelectric conversion material having a high figure-of-merit ZT, the thermoelectric conversion material being a p-type or n-type full-Heusler alloy, having a composition of an Fe2TiA type (wherein A is Si and/or Sn), and including crystal grains having an average grain diameter of 30-500 nm. In particular, in the case where the composition of an Fe2TiA type is represented by the empirical formula Fe2+Ti1+yA1+z, the values of , y, and z in an FeTi-A ternary alloy phase diagram lie within the range surrounded by the points (50, 37, 13), (45, 30, 25), (39.5, 25, 35.5), (50, 14, 36), (54, 21, 25), and (55.5, 25, 19.5) in terms of (Fe, Ti, A) in at %.

The invention relates to a method for producing a component from an at least partially amorphous metal alloy, comprising the following steps: providing a powder from an at least partially amorphous metal alloy; producing a shaped semi-finished product from the powder in that the powder is applied in layers and the powder particles of each newly applied layer, at least at the surface of the semi-finished product to be shaped, are fused and/or melted by targeted local heat input and bond to one another as they cool again; and hot pressing the semi-finished product, wherein the hot pressing is performed at a temperature that is between the transformation temperature and the crystallisation temperature of the amorphous phase of the metal alloy, wherein a mechanical pressure is exerted onto the semi-finished product during the hot pressing and the semi-finished product is compacted during the hot pressing.

The invention also relates to a component produced by such a method from a powder formed from an at least partially amorphous metal alloy and to the use of such a component as a gearwheel, friction wheel, wear-resistant component, housing, watch case, part of a gear unit, or semi-finished product.

The invention relates to a method for producing a component from an at least partially amorphous metal alloy, having the steps of: preparing a powder of an at least partially amorphous metal alloy, wherein the powder consists of spherical powder particles and the powder particles have a diameter of less than 125 m; pressing the powder into the desired shape of the component to be generated; compressing and sintering the powder by means of a heat treatment of the powder during pressing or after pressing at a temperature between the transformation temperature and the crystallisation temperature of the amorphous phase of the metal alloy, wherein the duration of the heat treatment is chosen such that the component is sintered after heat treatment and has an amorphous fraction of at least 85 percent. The invention also relates to a component made of a pressed, sintered, spherical, amorphous metal alloy powder, wherein the component has an amorphous fraction of at least 85 percent, and to the use of such a component as gear wheel, abrasive wheel, wear-resistant component, housing, watch casing, part of a gearing or semi-finished product.

The present invention provides a magnetic core part by which failures such as cracks do not occur even if the magnetic core part contains 90% by mass or more of an amorphous metal powder. The magnetic core part is formed by thermoset molding at least one magnetic powder selected from an amorphous metal powder alone and an amorphous metal powder coated with an insulating material, and a thermosetting binder resin. The magnetic core part contains the magnetic powder in an amount of 90% by mass or more and 99% by mass or less with respect to the total amount of the magnetic powder and the thermosetting binder resin.
