Abstract: Methods for forming a dual-phase magnetic component from an initial component comprising a non-magnetic austenite composition are provided. The method may include: forming a coating on a portion of the surface of the initial component to form a masked area while leaving an unmasked area thereon. Thereafter the initial component may be heated to a treatment temperature such that nitrogen diffuses out of the unmasked area of the initial component to transform the non-magnetic austenite composition to a magnetic phase in the unmasked area. Thereafter, the initial component may be cooled from the treatment temperature to form a dual-phase magnetic component having a magnetic region corresponding to the unmasked area and a non-magnetic region corresponding to the masked area.

Abstract: Methods for joining dissimilar high-temperature alloys are provided, along with articles, such as turbine airfoils, formed by the method. The method comprises interposing a barrier material between a first segment and a second segment to form a segment assembly. The first segment comprises a titanium aluminide material, and the second segment comprises a nickel alloy. The barrier material comprises a primary constituent element present in the barrier material at a concentration of at least about 30 weight percent of the barrier material, and the primary constituent element is a transition metal element of Group 1B, Group 4B (excluding titanium and zirconium), Group 5B, Group 6B, Group 7B, or Group 8B (excluding nickel). The segment assembly is bonded in the solid state at a combination of temperature, pressure, and time effective to produce a metallurgical joint between the first and second segments, thereby forming an intermediate article; and the intermediate article is heat treated to form a bonded article.
