Nitrex Metal Inc., Quebec, Canada, has installed a nitriding/nitrocarburizing system at Dongwoo HST Ltd., Korea. Primarily for processing Hyundai ring gears, it includes three Nitreg-based nitriding technologies for a variety of steel types with process recipes for each product application. Along with the increase in the ring gear business, Dongwoo is expanding to meet the growing demand in Korea for advanced heat treatments with superior capabilities.
Optomec Inc., Albuquerque, N.M., launches a low cost metal 3D printer named the LENS 450. The system was developed specifically in response to growing industry interest in 3D printing of metals, including the need to train a new generation of workers in metal additive manufacturing technology. The first delivery will be to the Department of Mechanical Engineering and Material Science at the University of Pittsburgh, where it will be used in its new Advanced Manufacturing education program.
ASM International, Materials Park, Ohio, and The Minerals, Metals & Materials Society (TMS), Warrendale, Pa., announced two new editors for the Metallurgical and Materials Transactions journals: Steven J. Zinkle, FASM, of Oak Ridge National Laboratory (ORNL) and Sridhar Seetharaman of the University of Warwick. Zinkle Named Editor for Metallurgical and Materials Transactions E Steven J.
Scientists at Stanford University, Calif., x-rayed a damaged musical score to reveal the musical notes hidden beneath a layer of black carbon. The beautifully bound 1797 Luigi Cherubini opera Médée looks like an impeccably preserved relic of opera’s golden age. However, the final pages of the aria “Du trouble affreux qui me dévore” (“The terrible disorder that consumes me”) are blackened with carbon that completely obscures the closing lines.
Researchers at Harvard and the Massachusetts Institute of Technology, Cambridge, teamed up to produce a 3D-printed inchworm robot made of shape memory polymers. The robot transforms itself from a completely flat, two-dimensional object into a walking inchworm-shaped robot with almost no help from human hands. Shape memory polymers fold along specific hinges; the only human input needed is to attach the battery and motor.
