Abstract: The present invention provides a cabinet (2) intended for transporting and distributing meal trays in aircraft, for example to provide a trolley (1) which can be reinforced with a frame (3). The cabinet is made of a fireproof, water-repellent, alveolate cardboard material, the cabinet comprising an upper face, a lower face, two side faces, a rear face, a front face forming a door, which are made of a single piece of cardboard. The invention also provides for the use of a flat sheet of cardboard, pre-cut in a structured manner, to form a cabinet in a single piece when folded and assembled, preferably of parallelepipedal shape, the sheet of cardboard having a thickness of 6 mm to 10 mm, and a method of manufacturing a cabinet comprising the provision of such a sheet of cardboard, to form a cabinet.

Abstract: Methods of producing three-dimensional alloy workpieces are described herein, which can comprise: producing a precursor workpiece on a layer-by-layer basis by depositing a layer of a mixed powder, the mixed powder comprising an elemental powder and a second powder; melting at least a portion of the elemental powder by directing an energy field onto a portion of the layer; and repeating the deposing and melting steps to form the precursor workpiece from a plurality of layers. The precursor workpiece can comprise a dispersed phase and a continuous phase, the dispersed phase being dispersed within the continuous phase, the dispersed phase comprising a plurality of discrete regions comprising the second powder, and the continuous phase comprising the melted elemental powder. The methods can further comprise heating the precursor workpiece to homogenize the continuous phase and the dispersed phase, thereby forming the three-dimensional alloy workpiece comprising a continuous alloy phase.
