A team of Massachusetts Institute of Technology engineers has successfully designed a new 3-D material with five percent the density of steel and ten times the strength, making it one of the strongest lightweight materials known.
The port of Rotterdam announces that it has opened the Rotterdam Additive Manufacturing Lab (RamLab), an onsite facility that includes a pair of six-axis robotic arms capable of additively manufacturing large metal industrial parts.
Braidy Industries Inc., Ashland, Kentucky, announces that it will spend $1.3 billion to build an auto body sheet and aerospace plate aluminum rolling mill, the nation’s first greenfield aluminum rolling mill in over three decades.
NIST, Gaithersburg, Md., announces that its scientists have developed a noninvasive “spectral fingerprint” terahertz radiation technique that reveals the corrosion of concrete-encased steel before it can cause any significant degradation of the structure it supports.
The microstructural feature responsible for the favorable technological properties resulting from low-temperature gaseous thermochemical treatment is a supersaturation of nitrogen and/or carbon in austenite. This is called expanded austenite.
