    Abstract: The present invention relates to a system for contactless induction of high-frequency vibrations in a volume of molten metal (1) during the manufacturing of a metal component or a metal matrix composite component. The system comprises a moveably arranged electromagnetic primary coil (2), adjustment means (3) for adjusting the position of the primary coil (2), and a control unit (5) for controlling the position of the primary coil (2) to a predefined distance above and not in physical contact with an upper free surface (4) of the molten metal (1) during use of the system. In some embodiments of the invention the molten metal (1) is contained in a foundry crucible (7) during manufacturing. In other embodiments, the system is used for an additive manufacturing system, so that the primary coil (2) is arranged above the melt pool (16). In both embodiments, a secondary low-frequency electromagnetic coil (9) may be arranged around and at a distance from the molten metal (1). This secondary coil (9) is used to induce flow and/or vibrations in the molten metal (1) which is particularly useful during manufacturing of large components.

    Abstract: The present invention relates to a method of manufacturing a component 1 by additive manufacturing. The method comprises providing a work surface 2 on which the component 1 is to be manufactured, and providing at least one deposition material 3 from which the component 1 is to be composed. The deposition material, typically in the form of wire, is advanced to a localized deposition area 4 where it is added to the component 1 being manufactured. The method further comprises focusing at least one light beam 5 of incoherent light emitted from at least one heating source 6 in the deposition area 4 so that the deposition material 3 is deposited for building up the component 1. At least one light focusing mirror 7 and/or lens 11 is used to focus the incoherent light in the deposition area 4. The invention further relates to the use of such a method in space, such as on a space station, on a space craft or on parabolic flights for testing.

    Abstract: The present invention relates to a method of manufacturing a metal matrix composite component (9). It comprises the use of a container (1) having a first compartment (2) and a second compartment (3) interconnected by a passage (4). A porous reinforcement preform (6) is placed in the first compartment (2), and matrix metal (7) is placed in the second compartment (3). The container (1) is then evacuated and sealed. The container (1) and its content is heated to above a melting temperature of the matrix metal (7) at least until the matrix metal (7) has melted. Then a high pressure P is applied to the outside of the container (1) so that at least the second compartment (3) is deformed to such an extent that melted matrix metal (7) is forced to flow via the passage (4) into the first compartment (2) and to infiltrate the porous reinforcement preform (6). The method may preferably be carried out in a hot isostatic pressure vessel (8). The preform (6) may be made from a ceramic or metal material and is typically made from one or more of the following: nanoparticles, microparticles, fibres, wires and 3D woven structure.
