摘要： A system may include a current source; a first metal or alloy component with a first major surface electrically coupled to the current source; a second metal or alloy component with a second major surface electrically coupled in series to the first component and the current source via an external electrical conductor, where the first and second major surfaces are positioned adjacent to each other to define a joint region; a metal or alloy powder disposed in at least a portion of the joint region; and a controller. The controller may be configured to cause the current source to output an alternating current that conducts through the first component and the second component to induce magnetic eddy currents, magnetic hysteresis, or both within at least a portion of the metal or alloy powder disposed in at least the first portion of the joint region.

摘要： A high-speed steel sintered body includes, a base, a solidified layer continuously disposed on a surface of the base. The base is constituted by high-speed steel, the solidified layer is constituted by high-speed steel whose composition is different from a composition of the high-speed steel constituting the base, and a boundary between the base and the solidified layer is not visually identified in a 200× magnified observation image of a section intersecting the surface.

摘要： A method of forming a component from a part in the green state, including selecting at least one first portion of the part to undergo a different local volume reduction from at least one second portion to obtain the component. The green part is provided with the first portion(s) having a first solid loading and the second portion(s) having a second solid loading different from the first solid loading, then debound and sintered to obtain the component. The different first and second solid loadings produce the different local volume reduction in the first portion(s). The first portion(s) can be selected by determining a resulting final shape obtained from debinding and sintering a green part having a uniform first volumetric proportion of binder, and selecting the first portion(s) requiring a different local deformation than that producing the resulting final shape to obtain a desired final shape.

摘要： Embodiments disclosed herein relate to the production of bulk amorphous metal (BAM) alloys comprising chromium, manganese, molybdenum, tungsten, silicon, carbon, boron, and the balance of iron to replace tungsten carbide-based welded material. The BAM alloy embodied herein can be applied through PTA welding, HVOF, TWAS, flame spraying, plasma spraying, laser, their combinations, and other coating and welding processes. When used as welded material, the density of the embodiment of around 7 grams per CC, which is less dense than the tungsten carbide customarily used, resulting in even hard faces during welding spread uniformly across the weld, therefore creating a harder and more wear-resistant weld.

摘要： A method for manufacturing a hollow part made of ceramic matrix or metal matrix composite, includes preparing a raw material including short fibers and a ceramic matrix precursor charge, positioning a sacrificial core in a molding cavity of injection-molding equipment, shaping the raw material by injection molding the raw material into the free space between the sacrificial core and an internal wall of the cavity to obtain a green part including the sacrificial core and the shaped raw material, extracting the green part from the equipment, densifying the raw material by flash sintering of the green part to transform the charge into a ceramic matrix, removing the sacrificial core to obtain a hollow part made of ceramic matrix or metal matrix composite, wherein the sacrificial core is coated with a flexible graphite sheet, with a graphite layer deposited by spraying or with a boron nitride paint layer before the injecting.
