Abstract: A method of manufacturing a three-dimensional target object may include forming a shell from loose machining powder using an additive manufacturing process and subjecting the shell to a densification process to form a target object. The shell may define an enclosure that contains additional machining powder. The densification process may include causing metallurgical bonding between the shell and additional machining powder contained in the enclosure defined by the shell and shrinking and/or distorting the shape of the shell to conform the target object to a three-dimensional model for the target object. The shell may include a plurality of layers and/or parts that differ at least in respect of density. The plurality of layers and/or parts may be configured based at least in part on the shrinking and/or distorting to the shape of the shell needed to conform the target object to the three-dimensional model for the target object.

Abstract: A method for manufacturing a three-dimensional part. The method includes: performing partial densification processing on loose machining powder, to form a densified and sealed enclosure, where there is still loose machining powder accommodated inside the enclosure; and performing overall densification processing on the enclosure and the machining powder inside the enclosure, so as to implement metallurgical bonding between the machining powder inside the enclosure and the enclosure during the densification, thereby forming a target three-dimensional part.

Abstract: A titanium-based component having a high heat capacity surface. The high heat capacity surface prevents or inhibits titanium fires. The component is titanium-based, forming the substrate, and includes a high heat capacity surface overlying the titanium substrate. A diffusion barrier is intermediate the titanium-based substrate and the high heat capacity surface. The diffusion barrier is non-reactive with both the titanium-based substrate and the high heat capacity surface. The system eliminates the formation of detrimental phases due to diffusion between the applied high heat capacity surface and the titanium substrate. The high heat capacity material has a coefficient of thermal expansion compatible with the coefficient of thermal expansion of the titanium-based substrate. The stresses introduced into the component as a result of differential thermal expansion between the high heat capacity material and the titanium-based substrate do not result in spalling of the substrate at the operational temperatures of the component.

Abstract: Process for producing a titanium alloy material, such as a titanium aluminum alloy, are provided. The process includes reduction of TiCl4, which includes a titanium ion (Ti4+), through intermediate ionic states of an AlCl3-based salt solution that includes Ti3+ and an AlCl3-based salt solution that includes Ti2+, which may then undergo a disproportionation reaction to form the titanium aluminum alloy.
