摘要： In exemplary implementations of this invention, an actuated fabricator deposits structural elements (e.g., tensile structural elements) in a 3D pattern over large displacements. The fabricator is supported by at least three elongated support members. It includes onboard actuators that translate the fabricator relative to the ends of the support members. The fabricator is configured, by actuating different translations along different support members, to translate itself throughout a 3D volume. In some implementations, each of the actuators use fusible material to fuse metal tapes together, edge-to-edge, to form a hollow structure that can be shortened or lengthened.

摘要： A pulling-up-type continuous casting apparatus includes a holding furnace that holds molten metal, a shape defining member disposed above a surface of the molten metal held in the holding furnace, and configured to define a cross-sectional shape of a cast-metal article as the molten metal passes through it, an image pickup unit that takes an image of the molten metal that has passed through the shape defining member, an image analysis unit that detects a fluctuation on the molten metal from the image and determines a solidification interface based on presence/absence of the fluctuation, and a casting control unit that changes a casting condition only when the solidification interface determined by the image analysis unit is not within a predetermined reference range. The casting control unit uses a reference range which differs according to the pulling-up angle of the molten metal.

摘要： Embodiments herein relate to a method for forming a bulk solidifying amorphous alloy sheets have different surface finish including a “fire” polish surface like that of a float glass. In one embodiment, a first molten metal alloy is poured on a second molten metal of higher density in a float chamber to form a sheet of the first molten that floats on the second molten metal and cooled to form a bulk solidifying amorphous alloy sheet. In another embodiment, a molten metal is poured on a conveyor conveying the sheet of the first molten metal on a conveyor and cooled to form a bulk solidifying amorphous alloy sheet. The cooling rate such that a time-temperature profile during the cooling does not traverse through a region bounding a crystalline region of the metal alloy in a time-temperature-transformation (TTT) diagram.

摘要： Embodiments of this apparatus and method introduce solutes into a sheet formed from a melt. A melt of a material is cooled and a sheet of the material is formed in the melt. A first fluid is introduced around the sheet at least partially while the sheet is formed. A second fluid also may be introduced. In one instance, use of the first fluid and second fluid may form a sheet that has two different solute concentrations.
