A thin-skin side-stay beam may include an upper arm with thin skin and a mating flange extending longitudinally from the thin skin. A lower arm may also have a thin skin and a mating flange extending longitudinally from the lower arm. A joint may include a pin and/or a bushing extending through the mating flanges to pivotally couple the upper arm to the lower arm. The upper arm and/or the lower arm may include one or more internal walls defining one or more internal cavities.

A system for generating a user-adjustable furnace profile, comprises a user interface configured to receive one or more materials properties from a user, a processor, and a memory with computer code instructions stored thereon. The memory is operatively coupled to the processor such that, when executed by the processor, the computer code instructions cause the system to implement communicating with a furnace to ascertain one or more thermal processes associated with the furnace, identifying one or more object characteristics associated with an object to be processed by furnace, and determining a thermal processing parameter profile of at least one thermal processing parameter corresponding to each of the thermal processes, based on (i) the one or more part characteristics and (ii) the one or more materials properties, the thermal processing parameter profile characterizing a cycle of the one or more thermal processes.

A heat treatment method for an additive manufactured object formed of a laminate-molded Ni-base alloy includes: a heat treatment step for carbide precipitation optimization of heating the additive manufactured object for 1 hour or longer and 100 hours or shorter at a temperature which is equal to or higher than a temperature T1 determined by Formula (1) according to amounts of component elements and is equal to or lower than 1,350° C.; and an aging treatment step of heating the additive manufactured object for 1 to 30 hours at a temperature of 800° C. to 950° C. after the heat treatment step for carbide precipitation optimization.
T1 (° C.)=177×Ni (%)+176×Co (%)+172×Cr (%)+178×Mo (%)+174×W (%)+171×Al (%)+170×Ti (%)+168×Ta (%)+163×Nb (%)+307×C (%)−16259  (1)

A method of making a 3D printed cermet or cemented carbide body including a hard phase and a metallic binder phase whereby the 3D printed green body is subjected to a sintering process including a holding step prior to a liquid phase sintering step. The sintered bodies have a reduced porosity.

An apparatus is disclosed to create a breakaway junction for 3D printed parts. Powder is spread along a target zone, such as a build bed. A liquid functional agent is selectively dispensed upon the powder to form a 3D object, a supporting part, and the breakaway junction between them.

Graphite-containing brass alloy billets having less than 0.25 wt. % lead and a method of manufacturing relating thereto are provided. The method includes forming a brass powder and mixing the brass powder with graphite and one or more binders. The brass powder contains copper and zinc and may be formed using water atomization. The brass-powder mixture is compacted to form an initial billet. The initial billet may be subjected to one or more heating treatments. A first heating treatment may be used to remove the one or more binders. An optional second heating treatment may be used to deoxidize the binder-free billet. An optional third heating treatment that includes applying a pressure may be used to densify the binder-free billet. A third heating treatment may sinter the compact to form the workable graphite-containing brass alloy billet.

Methods for die attachment of multichip and single components including flip chips may involve printing a sintering paste on a substrate or on the back side of a die. Printing may involve stencil printing, screen printing, or a dispensing process. Paste may be printed on the back side of an entire wafer prior to dicing, or on the back side of an individual die. Sintering films may also be fabricated and transferred to a wafer, die or substrate. A post-sintering step may increase throughput.

According to the present disclosure, there is provided a method for smoothing a surface of an additively manufactured metal part. The method comprises applying a chemical to a stepped surface of an additively manufactured part to at least soften a binder material supporting unprocessed powder particles of the part and allowing the powder particles at the surface to flow under the influence of gravity into recesses defined by the stepped surface to thereby reduce a roughness of the surface. Advantageously, it has been found that the afore-described method is able to provide a part having an improved surface smoothness.
