How to 3D-Print One of the Strongest Stainless Steels
For airliners, cargo ships, nuclear power plants and other critical technologies, strength and durability are essential. This is why many contain a remarkably strong and corrosion-resistant alloy called 17-4 precipitation hardening stainless steel. Now, for the first time ever, 17-4 PH steel can be consistently 3D-printed while retaining its favorable characteristics.

Machine Learning Reduces Hazards in Nuclear Power Plants
The application of machine learning with simulation data will provide additional possibilities for field engineers to more accurately assess the hazards for their specific plant. Field conditions are typically not the same as data set conditions. Machine learning models developed in this research will be able to rapidly translate what the appropriate hazard event conditions are for the given field conditions.

Engineers Mix and Match Materials to Make New Stretchy Electronics
At the heart of any electronic device is a cold, hard computer chip, covered in a miniature city of transistors and other semiconducting elements. Because computer chips are rigid, the electronic devices that they power, such as our smartphones, laptops, watches, and televisions, are similarly inflexible. Now a process developed by engineers may be the key to manufacturing flexible electronics with multiple functionalities in a cost-effective way.
