Abstract: A method for producing a three-dimensional object (2) by applying layers of a pulverulent construction material (11) and by selectively solidifying said material by the action of energy comprises the steps: a layer of the pulverulent construction material (11) is applied to a support (6) or to a layer of the construction material that has been previously applied and at least selectively solidified; an energy beam (14) from an energy source (13) sweeps over points on the applied layer corresponding to a cross-section of the object (2) to be produced in order to selectively solidify the pulverulent construction material (11); and a gas flow (18) is guided in a main flow direction (RG) over the applied layer during the sweep of the energy beam (14). The main flow direction (RG) of the gas flow (G) and the sweep direction (RL) of the energy beam (14) are adapted to one another at least in one region of the cross-section to be solidified.

Abstract: A composite magnetic material contains metal magnetic powder composed of metal magnetic particles, and mica interposed between the metal magnetic particles as an inorganic insulator. The mica has an Fe content of 15 wt% or less per 100 wt% of the mica in terms of Fe 2 O 3 . To manufacture the composite magnetic material, first, mixed powder is prepared by mixing the metal magnetic powder and the mica so as to be dispersed into each other. Next, a compact is formed by pressure-molding the mixed powder. Finally, the compact is heat-treated.
