Abstract: Disclosed are a nickel-based superalloy formed by selective laser melting and a preparation method thereof. In the method, CrFeNb alloy powder is used as a grain refiner, and its element composition is within the composition range of a nickel-based superalloy powder to ensure that the prepared nickel-based superalloy has the same element composition with the original alloy; the grain size in the nickel-based superalloy could be refined by the addition of CrFeNb alloy powder, such that the anisotropic columnar grain structure in the alloy is transformed to equiaxed grain structure, thereby improving mechanical properties of the alloy.

Abstract: Methods of creating golf club components with complex structures that would be difficult, impossible, or cost prohibitive to produce, such as lattice structures, beam structures, and complex surface-based structures, are described herein. In particular, a binder jet machine is used create complex structures to optimize weighting, sound, and performance of golf club heads. The method preferably includes the steps of designing a golf club head component in CAD using optimization software, printing the component from a powdered material, and then removing excess powder from the component via port holes that extend into an external surface of the component and communicate with interior voids within the component.

Abstract: Provided are a jet device and systems and methods using the jet device for manufacturing objects by additive manufacturing, especially titanium and titanium alloy objects, wherein the jet device directs a cooling gas across a liquid molten pool, or to impinge on the liquid molten pool, or to impinge upon a solidified material adjacent to a liquid-solid boundary of the liquid molten pool, or to impinge on an as-solidified material, or any combination thereof, during the additive manufacturing process. The application of the cooling gas can result in an additively manufactured metal product having refined grain structure with a high proportion of the grains being approximately equiaxed, and can yield an additively manufactured product exhibiting improvements in strength, fatigue resistance, and durability.
