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: Methods of forming an intermediate alloy and a Ni-base super alloy are disclosed along with the intermediate alloy and the Ni-base super alloy formed by the method. The method includes at least partially melting and solidifying a powder including about 5 to 15 wt. % of Co, 10 to 20 wt. % of Cr, 3 to 6 wt. % of Mo, 3 to 6 wt. % of W, 2 to 4 wt. % of Al, 4.2 to 4.7 wt. % of Ti, 0.01 to 0.05 wt. % of Zr, 0.015 to 0.060 wt. % of C, 0.001 to 0.030 wt. % of B and balance substantially Ni to form an intermediate alloy including a dendrite structure that includes columnar regions and intercolumnar regions and a primary dendrite arm spacing less than about 3 micrometers. The intermediate alloy is heat-treated to form the texture-free Ni-base super alloy.

Abstract: A control system for use in an additive manufacturing system. A recoating device is configured to distribute powder for forming a component and a recoating motor is configured to move at least one of the powder bed and the recoating device relative to each other. The control system includes at least one vibration sensor configured to collect vibration data, a torque sensor coupled to the recoating motor and configured to collect the torque output data, and an optical sensor configured to collect reflected light data. The control system includes a controller configured to receive the vibration data, receive the torque output data, and receive the reflected light data, the controller further configured to determine at least one powder bed characteristic based on at least one of the data, and control at least one recoating parameter of the recoating device based on the at least one determined powder bed characteristic.

Abstract: A method for reducing surface roughness of an article includes contacting a surface of an article with a molten metal agent, the surface having an initial roughness; altering at least a portion of the surface in the molten metal agent; and removing the surface from contact with the agent; wherein, after the removing step, the surface has a processed roughness that is less than the initial roughness.

Abstract: A magnetic component having intermixed first and second regions, and a method of preparing that magnetic component are disclosed. The first region includes a magnetic phase and the second region includes a non-magnetic phase. The method includes mechanically masking pre-selected sections of a surface portion of the component by using a nitrogen stop-off material and heat-treating the component in a nitrogen-rich atmosphere at a temperature greater than about 900° C. Both the first and second regions are substantially free of carbon, or contain only limited amounts of carbon; and the second region includes greater than about 0.1 weight % of nitrogen.
