摘要： A method for making an article is disclosed. According to the method, a digital model of the article is generated. The digital model is inputted into an additive manufacturing apparatus comprising an energy source. The additive manufacturing apparatus applies energy from the energy source to successively applied incremental quantities of a powder to fuse the powder to form the article corresponding to the digital model. The powder particles individually include a composite core including a first phase of a first metal and a second phase of a ceramic. A first shell including a second metal is disposed over the core.

摘要： A method for preparing a precoated sheet is provided. The method includes providing a precoated sheet having a metallic substrate with a precoating on at least one of its faces and removing through laser ablation at least a portion of the precoating on the at least one face of the precoated sheet in a removal zone. The ablation step is carried out in an installation. The installation includes at least one protective element having a protective surface. During the ablation step, the protective surface contacts the precoated sheet in a contact area in register with the laser beam as the laser beam removes the portion of the precoating. A plane tangent to the protective surface at the contact area forms a dihedral angle with the plane of the face of the precoated sheet. This angle is strictly smaller than 90°.

摘要： A method for producing a hot-rolled clad composite material may involve cleaning surfaces of multiple flat products, at least one surface of which has a natural unevenness. The cleaned surfaces may then be connected and brought into contact by stacking the flat products. The flat products may then by regionally welded to create a flat product package. The method may further involve heating the flat product package to an initial hot-rolling temperature, hot-rolling the flat product package to form a hot strip, and either cutting the hot strip into plates or sheets or coiling the hot strip to form a coil.

摘要： A multilayer steel includes a core formed of transformation-induced plasticity (TRIP) steel. A decarburized layer is exterior to the core on at least one side thereof. The decarburized layer has reduced carbon content relative to the core. A zinc-based layer is exterior to the decarburized layer. The decarburized layer may have a composition of at least 80 percent ferrite, such that LME is reduced or mitigated. In some configurations, the decarburized layer is between 10-50 microns thick. A method of creating a coated advanced high-strength steel component is also provided. An apparatus for forming a coated advanced high-strength steel is also provided. The core of the multilayer steel may have a carbon weight-percent of less than or equal to 0.4. The decarburized layer of the multilayer steel may have a carbon weight-percent of less than or equal to 50 percent of the carbon weight-percent of the core.

摘要： In the present invention, while a welding current is applied with respect to a laminate body comprising thick metal plates and thin metal plates, a first welding pressure (F1) with respect to the laminate body from an upper tip contacting the metal plate and a second welding pressure (F2) with respect to the laminate body from a lower tip contacting the metal plate are changed relative to each other. Specifically, F1 F2 in a third step which is a final period of welding.

摘要： A method of bonding two components includes plating a first of the components with a first silver layer, a tin layer, and a second silver layer, plating a second of the components with silver, inserting the first and second components into a pre-heated press, and applying pressure to the components causing the components to bond. A stack of layers has a first component layer, a first silver layer, a tin layer, a second silver layer, a second component silver layer, and a second component layer.

摘要： A 3D printer that is mostly twenty to thirty times faster than existing 3D printers. Pixel-based Raster images are converted into Scalable Vector Graphic (SVG) images, which are then categorized as lines, curves and surface areas. For each category, faster printing methods for printing with pre-formed shapes such as rods, boards, arcs, etc., are disclosed. Pre-formed shapes may be made of plastic/thermoplastic/polymer or sintering materials, as desired. Sintering materials may be cladded/coated with appropriate materials such as solder, copper, and thermoplastics. The new print-head, which has a fixed portion and a replaceable portion, has a mechanism to draw upon pre-formed shapes to print. The replaceable portion has varying shapes and sizes of placement holes, and a mechanism to signal which replaceable portion has been mounted. The print-head incorporates mechanisms to heat and tack the pre-formed shapes. The invention discloses methods to use multiple print-heads to further speed up printing.

摘要： A method includes generating a plurality of pulse bursts with a predetermined quantity of intra-burst pulses in each pulse burst and a temporal spacing between the intra-burst pulses, and with a pulse burst frequency, and scanning the pulse bursts across an anodized target at a scan rate so that the pulse bursts overlap at the anodized target by an amount that is above an overlap damage threshold and the intra-burst pulses provide a peak power and peak fluence that are below an ablation threshold of the anodized target so as to produce a laser mark on the anodized target with an L value of less than or equal to 30 and without a damage to an anodized layer of the anodized target.
