Boron can enhance mechanical properties of steel, but too much boron will segregate from the steel and negate these benefits. Researchers led by Wuhan University of Science and Technology looked to enhance the toughness of high boron steel using a novel processing technique called quenching and partitioning.

Determining oxidation stability of new MAX phases is a difficult and expensive process with current computational and experimental methods. Researchers at Texas A&M University designed a new machine-learning-based scheme for predicting the oxidation of MAX phases at high temperatures, allowing them to conduct studies that may otherwise take years to perform.

MAX phases are layered ceramic materials with both ceramic and metal-like properties, as well as good radiation tolerance, making them ideal candidates for use in next-generation nuclear power technologies. Two recent papers investigate the irradiation of Cr2AlC to determine its potential for this application.

For successful nuclear nonproliferation initiatives, authorities must be able to detect and characterize radioactive sources—but how can they do so if the radioactive material was removed before they arrived? Researchers at North Carolina State University developed a technique that allows retrospective characterization of radioactive sources.
