Method for manufacturing a thin strip in a soft magnetic alloy and strip obtained A method for manufacturing a strip in a soft magnetic alloy capable of being cut out mechanically, the chemical composition of which comprises by weight: TABLE-US-00001 18% ≤ Co ≤ 55% 0% ≤ V + W ≤ 3% 0% ≤ Cr ≤ 3% 0% ≤ Si ≤ 3% 0% ≤ Nb ≤ 0.5% 0% ≤ B ≤ 0.05% 0% ≤ C ≤ 0.1% 0% ≤ Zr + Ta ≤ 0.5% 0% ≤ Ni ≤ 5% 0% ≤ Mn ≤ 2% The remainder being iron and impurities resulting from the elaboration, according to which a strip obtained by hot rolling is cold-rolled in order to obtain a cold-rolled strip with a thickness of less than 0.6 mm. After cold rolling, a continuous annealing treatment is carried out by passing into a continuous oven, at a temperature comprised between the order/disorder transition temperature of the alloy and the onset temperature of ferritic/austenitic transformation of the alloy, followed by rapid cooling down to a temperature below 200° C. Strip obtained.

A device includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough. The capsule is releasably coupled to a proximal portion of the device. Device also includes a first arm rigidly fixed to the distal end of the capsule to extend distally therefrom. In addition, Device includes a second arm, a proximal end of which is slidably received within the capsule so that the second arm is movable between an open configuration, in which the second arm is moved laterally away from the first arm and a distal end of the second arm is moved distally past the distal end of the first arm, and a closed configuration, in which the second arm is moved toward the first arm and the distal end of the second arm is moved proximally toward the distal end of the first arm.

Methods for direct writing of single crystal super alloys and metals are provided. The method can include: heating a substrate positioned on a base plate to a predetermined temperature using a first heater; using a laser to form a melt pool on a surface of the substrate; introducing a superalloy powder to the melt pool; measuring the temperature of the melt pool; receiving the temperature measured at a controller; and using an auxiliary heat source in communication with the controller to adjust the temperature of the melt pool. The predetermined temperature is below the substrate's melting point. The laser and the base plate are movable relative to each other, with the laser being used for direct metal deposition. An apparatus is also generally provided for direct writing of single crystal super alloys and metals.
