NASA used ResonantAcoustic mixing and additive manufacturing to synthesize an alloy they termed GRX-810, which survived temperatures over 1,090 °C (1,990 °F). The alloy also featured improved strength, malleability, and durability. The printer dispersed oxide particles uniformly throughout the metal matrix.
SLM-based additive manufacturing of nickel superalloys still poses significant challenges due to these alloys’ complex composition. With multiple alloying elements and high aluminum/titanium fraction, these materials, when consolidated through SLM form various secondary phases, which affects the processability and leading to weakness within ...
Originally developed to produce oxide-dispersion strengthened (ODS) nickel- and iron-base superalloys for applications in the aerospace industry, [1] MA has now been shown to be capable of synthesizing a variety of equilibrium and non-equilibrium alloy phases starting from blended elemental or pre-alloyed powders. [2]
Laser metal deposition (LMD) is an additive manufacturing process in which a feedstock material (typically a powder) is melted with a laser and then deposited onto a substrate. [1] A variety of pure metals and alloys can be used as the feedstock, as well as composite materials such as metal matrix composites.
This is a list of named alloys grouped alphabetically by the metal with the highest percentage. Within these headings, the alloys are also grouped alphabetically. Some of the main alloying elements are optionally listed after the alloy names.
Nickel superalloy jet engine turbine blade. A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. [1] Key characteristics of a superalloy include mechanical strength, thermal creep deformation resistance, surface stability, and corrosion and oxidation resistance.
Nickel alloys are alloys with nickel as principal element. Subcategories. This category has the following 3 subcategories, out of 3 total. A. Nickel–aluminium ...
A wide range of engineering alloys are compatible with the EBDM process and are readily available in the form of welding wire from an existing supply base. These include, but are not limited to, stainless steels, cobalt alloys, nickel alloys, copper nickel alloys, tantalum, titanium alloys, as well as many other high-value materials. [citation ...
