Abstract: A dual phase magnetic component, along with methods of its formation, is provided. The dual phase magnetic component may include an intermixed first region and second region formed from a single material, with the first region having a magnetic area and a diffused metal therein, and with the second region having a non-magnetic area. The second region generally has greater than 0.1 weight % of nitrogen.

Abstract: Rhenium-free nickel based alloys are provided. More particularly, the alloys comprise preferred levels and ratios of elements so as to achieve good high temperature strength of both gamma matrix phase and gamma prime precipitates, as well as good environmental resistance, without using rhenium. When cast and directionally solidified into single crystal form, the alloys exhibit creep and oxidation resistance substantially equivalent to or better than rhenium-bearing single-crystal alloys. Further, the alloys can be processed by directional solidification into articles in single crystal form or columnar structure comprising fine dendrite arm spacing, e.g., less than 400 μm, if need be, so that further improvements in mechanical properties in the articles can be seen.
Abstract translation: 提供无铼镍基合金。 更具体地，合金包括优选的含量和元素比例，以便在不使用铼的情况下实现γ基质相和γ初始沉淀物的良好的高温强度以及良好的耐环境性。 当铸造和定向凝固成单晶形式时，合金具有基本上等于或优于含铼单晶合金的蠕变和抗氧化性能。 此外，如果需要，合金可以通过定向固化加工成单晶形状或柱状结构的制品，包括细小的枝晶臂间距，例如小于400μm，从而可以看到制品中机械性能的进一步改善。

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: A nickel-based braze alloy composition includes nickel, about 1 weight % to about 5 weight % boron (B); and about 1 weight % to about 20 weight % germanium (Ge). The composition is free of any silicon. Superalloy articles having a crack or other type of void or gap may be filled with the nickel-based braze alloy composition. Methods for filling such a gap are described.

Abstract: A method of forming titanium-based spherical metallic particles includes performing a hydride-dehydride process on a meltless metallic sponge to form a feedstock material including a metallic powder. The method further includes introducing the feedstock material into a microwave plasma discharge to form the titanium-based spherical metallic particles.
