The Defense Department recently announced that the Department of the Navy awarded Sikorsky with a $1.13 billion contract for 12 CH-53K heavy-lift helicopters. The Navy plans to purchase 200 of these aircraft over the life of the program.
During the Paris Air Show, GE Additive announced a significant investment in Arcam electron-beam melting (EBM) technology. An additional 27 EBM systems will be purchased, which brings the total number of units to 62. They will be used to produce titanium-aluminide (TiAl) blades for the low-pressure turbine of the GE9X engine.
Roll-Royce has added an AM system produced by SLM Solutions AG to advance AM technology for aerospace components. Additionally, GKN Aerospace has commissioned a second large-scale pilot production facility at the DOE’s Oak Ridge National Laboratory (ORNL).
It turns out that a person’s remains do not have to be stored in an urn after cremation. If you can believe it, the ashes of the dead can be forged into diamonds. This is possible because carbon is the second-most abundant element in the body, and diamonds are made of crystallized carbon.
Energy Secretary Rick Perry announced $89 million to support innovative, advanced manufacturing research and development projects. The Department of Energy Funding Opportunity announcement (FOA) requests proposals in three areas that will improve the global competitiveness of the U.S. by catalyzing innovation around manufacturing of key energy technologies and by reducing industrial process energy intensity.
A golf equipment company is using a multi-step forging process to manufacture a line of putters. Ben Hogan Golf Equipment Co. introduced four new models that are CNC precision-milled from soft, 1020 carbon steel in a multi-step forging process that strengthens and purifies the molecular structure of the metal to give consistent distance control across the face.
The Canadian government updated regulations on railroad tank cars transporting toxic inhalation hazard (TIH) substances. Effective July 2021, the head and shell of these railcars will be required to be made of normalized steel. The service life of the cars will be extended to 50 years, which is consistent with the United States.
Cummins Inc. added to its additive manufacturing (AM) capabilities by investing in binder jetting, a technology where a print head moves across a bed of powder and selectively deposits a liquid binding agent in the shape of the section, bonding these areas together to form a solid part one layer at a time.
According to this article, China could potentially cut off supplies of critical materials needed by large portions of the U.S. economy. In fact, the idea of China banning exports of rare-earth elements to the U.S. is possible. This is big news because U.S. oil refiners rely on rare-earth imports as catalysts to turn crude oil into gasoline.
Can salt – not the kind you put on your food – be used to store heat? A thermal power station in Germany is testing the theory, which goes like this: When calcium oxide becomes wet, the salt-like grains soak up the water, becoming calcium hydroxide and releasing large amounts of heat in the process.
