MIT researchers have devised a new method for shrinking the size of crystals to make safer metal alloys. The new materials could replace metal coatings such as chromium, which is dangerous for factory workers to produce.
The method, developed by Associate Professor Christopher Schuh and graduate student Andrew Detor, both of the Department of Materials Science and Engineering, involves making the crystals within an alloy (a combination of two or more metals) smaller and thus harder.
For the chromium replacement, the two made crystals of nickel and tungsten small enough that the resulting alloy is as hard as chromium. The trick is a new twist on electroplating that involves manipulating -- on the nanoscale, or billionths of a meter -- how the nickel and tungsten atoms are laid down as they are plated onto another metal.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
