    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.

    Abstract translation: 通过首先在基材的表面上设置富镍区域，然后用铝富集富镍区域以形成镀铝区域，并最终除去至少一部分镀铝区域形成物品的表面，从而形成 衬底的经处理的表面。 在去除这种材料后，表面的粗糙度从较高的初始粗糙度值降低到较低的加工粗糙度值。 在一些实施例中，加工的粗糙度小于初始粗糙度的约95％。 此外，本文所述的步骤的顺序可以重复一次或多次以实现衬底表面粗糙度的进一步降低。

    Abstract: Additive manufacturing methods, and articles made using additive manufacturing methods, are described herein. One embodiment is an article that comprises a hafnium-bearing superalloy. The superalloy includes at least about 50 weight percent nickel, from about 0.015 weight percent to about 0.06 weight percent carbon, and up to about 0.8 weight percent hafnium. The article further includes a plurality of primary carbide phase particulates disposed within the superalloy; the plurality has a median size less than about 1 micrometer. A method includes melting and solidifying particulates of a metal powder feedstock to build an intermediate article comprising a series of layers of solidified material. The feedstock includes the above-described superalloy composition. The method further includes heating the intermediate article to a temperature of at least about 950 degrees Celsius to form a processed article. The processed article further includes a plurality of primary carbide phase particulates disposed within the solidified material, the plurality of particulates having a median size less than about 1 micrometer.
