An Austrian specialty metals’ producer- Bohler Edelstahl - is now operating the world’s largest radial forging machine. The RF100 from American GFM features a maximum forging force of 2000 metric tons. Forging with varying stroke frequencies and rotation angles can create a well-worked core structure as well as improved surface quality. One of the reported benefits is improved microstructure, an important feature for critical aerospace and oilfield applications. One goal is to produce large round bars and billets of nickel alloy 718, 625 and Waspaloy. Bohler Edelstahl, which dates to 1860, focuses on production of high speed steels, tool steels and special materials, concentrating on highly demanding applications. The new generation radial forging machines type RF from GFM combine the technologies of a mechanical eccentric press with that of a hydraulic press.
The amount of plastic clogging the ocean continues to grow. Some startling, not-so-good news has come out recently about the roles plastic is playing in the ocean, as well as more heartening news about efforts to collect and reuse it.
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
