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 ...
Using a mixture of elemental and master alloy powders (the latter to reduce the activity of the element, since it is known that the activity in an alloy or a compound could be orders of magnitude less than in a pure metal) Eliminating the use of surface-active agents which would produce fine pyrophoric powder as well as contaminate the powder
The Unified Numbering System for Metals and Alloys (UNS) is an alloy designation system widely accepted in North America.Each UNS number relates to a specific metal or alloy and defines its specific chemical composition, or in some cases a specific mechanical or physical property.
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.
Regardless of what your thoughts are on Subway, you have to admit that the fast food chain proudly holds its footlong crown high.After solidifying its place in fast food lore with those beloved $5 ...
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 ...
(The Center Square) – A new Republican oversight report accuses former Congresswoman Liz Cheney of colluding with witnesses in the Jan. 6 Select Committee investigation that she oversaw. The ...
