Materials, methods and techniques disclosed and contemplated herein relate to aluminum alloys. Generally, multicomponent aluminum alloys include aluminum, magnesium, silicon, and, in some instances, iron and/or manganese, and include Mg2Si phase precipitates. Example multicomponent aluminum alloys disclosed and contemplated herein are particularly suited for use in additive manufacturing operations.

Al&#x2014;Mg&#x2014;Si alloys for applications such as additive manufacturing

Materials, methods and techniques disclosed and contemplated herein relate to multicomponent aluminum alloys. Generally, multicomponent aluminum alloys include aluminum, nickel, zirconium, and rare earth elements, and include Lprecipitates having an AlX composition. Rare earth elements used in example multicomponent aluminum alloys disclosed and contemplated herein include erbium (Er), zirconium (Zr), yttrium (Y), and ytterbium (Yb). Example multicomponent aluminum alloys disclosed and contemplated herein are particularly suited for use in additive manufacturing operations.

Multicomponent aluminum alloys for applications such as additive manufacturing

Alloys, processes for preparing the alloys, and articles including the alloys are provided. The alloys can include, by weight, about 4% to about 7% aluminum, 0% to about 0.2% carbon, about 7% to about 11% cobalt, about 5% to about 9% chromium, about 0.01% to about 0.2% hafnium, about 0.5% to about 2% molybdenum, 0% to about 1.5% rhenium, about 8% to about 10.5% tantalum, about 0.01% to about 0.5% titanium, and about 6% to about 10% tungsten, the balance essentially nickel and incidental elements and impurities.

Highly processable single crystal nickel alloys

Aluminum alloys are provided. The alloys can include one or more of zinc, magnesium, copper, zirconium, yttrium, erbium, ytterbium, scandium, silver, and the balance of aluminum and incidental elements and impurities. The alloys can be used for additive manufacturing of various articles, such as aircraft components.

Aluminum alloys

In one embodiment of the present disclosure, a niobium metal alloy composition includes: a vanadium content in the range of about 1.5 to about 12 weight percent; a hafnium content in the range of about 5 to about 13 weight percent; a titanium or zirconium content or a mixture of titanium and zirconium content in the range of about 0.25 to about 2.5 weight percent; and a niobium content as a balance of the alloy.

Niobium metal alloy

Alloys, processes for preparing the alloys, and articles including the alloys are provided. The alloys can include, by weight, about 0.01% to about 1% vanadium, 0% to about 0.04% carbon, 0% to about 8% niobium, 0% to about 1% titanium, 0% to about 0.04% boron, 0% to about 1% tungsten, 0% to about 1% tantalum, 0% to about 1% hafnium, and 0% to about 1% ruthenium, the balance essentially molybdenum and incidental elements and impurities.

Ductile high-temperature molybdenum-based alloys

A martensitic stainless steel alloy is strengthened by copper-nucleated nitride precipitates. The alloy includes, in combination by weight percent, about 10.0 to about 12.5 Cr, about 2.0 to about 7.5 Ni, up to about 17.0 Co, about 0.6 to about 1.5 Mo, about 0.5 to about 2.3 Cu, up to about 0.6 Mn, up to about 0.4 Si, about 0.05 to about 0.15 V, up to about 0.10 N, up to about 0.035 C, up to about 0.01 W, and the balance Fe and incidental elements and impurities. The nitride precipitates may be enriched by one or more transition metals. A case hardened, corrosion resistant variant has a reduced weight percent of Ni, enabling increased use of Cr, and decreased Co.

Martensitic stainless steel strengthened by copper-nucleated nitride precipitates

Alloys, a process for preparing the alloys, and manufactured articles including the alloys are described herein. The alloys include, by weight, about 11.5% to about 14.5% chromium, about 0.01% to about 3.0% nickel, about 0.1% to about 1.0% copper, about 0.1% to about 0.2% carbon, about 0.01% to about 0.1% niobium, 0% to about 5% cobalt, 0% to about 3.0% molybdenum, and 0% to about 0.5% titanium, the balance essentially iron and incidental elements and impurities.

Surface hardenable stainless steels

A device is shown for securing the base portion of a channel member of the type used to support a partition in a building to a ceiling grid structure. The device includes a bracket which is received on the ceiling structure. The channel member is secured to the bracket to support the channel member from the ceiling grid structure without damaging or contacting the ceiling grid structure itself. The bracket is then fastened to the ceiling grid structure to prevent transverse movement of the channel member along the ceiling grid structure. That portion of the ceiling grid structure which is visible within the completed building interior is not damaged when the partition is removed or relocated.
