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 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: A surface of an article is modified by first disposing a nickel-enriched region at the surface of a substrate, then enriching the nickel-enriched region with aluminum to form an aluminized region, and finally removing at least a portion of the aluminized region to form a processed surface of the substrate. Upon removal of this material, the roughness of the surface is reduced from a comparatively high initial roughness value to a comparatively low processed roughness value. In some embodiments, the processed roughness is less than about 95% of the initial roughness. Moreover, the sequence of steps described herein may be iterated one or more times to achieve further reduction in substrate surface roughness.
