Abstract
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.
